Hi all, Hoping someone can help me. I added a second SSD to my Unraid 6.8.1 server on Monday. I now have a 128GB SSD and a 120GB SSD in a btrfs cache pool. Seemed to go absolutely fine, balance happened leaving a total available space showing on the cache of 248GB with 141GB used. NOTE: I have an issue with the UDMA CRC error count on 'Cache' - it was not presenting any issues prior to the move to a pool. I have changed SATA cables since the error first presented itself and the count is stable. Balance status shows this: which based on searching, seem to be correct. However... on boot up my server is not allowing docker to run. Fix common problems is throwing the following errors: So I try to stop the server to diagnose / investigate. But it is now stuck 'retrying unmounting disk shares' Going into terminal, I do ls /mnt This shows only 2 remaining shares/mounted points. Theres nothing in disks, just a hangover from unassigned devices which I use to mount a usb drive for backup. The USB device is showing as unmounted in the GUI and does not show up in /mnt/disks. Then lsof /mnt/cache & lsof /mnt/disks But nothing is showing at all. I'm far from an expert in linux/unraid but I think I'm doing all the right things. I can't get any further, HELP! The critical cause here is the creation of the cache pool having borked my server because it now thinks it is full... Thanks in advance.

Hey, The mapping for the config all seemed correct, I had it mapped to mnt/cache/unraidapps/nowshowing The log was flagging that the plex user/password was incorrect. I triple checked it and it wasn’t. Then changed to the plex token option and still no change in behaviour. In the end I removed the docker, deleted the nowshowing config folder and reinstalled. Now working absolutely perfectly! I assume I had corrupted/affected something on the 1st install. Sorry I can’t help diagnose exactly what it was. Thanks again for the docker! Phil

Sorry it should have read: docker exec nowshowing combinedreport -t Autocorrect in these cases really doesn't help Thanks, Phil

Hi, I’m getting the following error when trying to run the following command via telnet: docker exec nowshowing combined report -t Configuration file not found. Exiting... advanced.yaml is where I would expect it to be, config all set up correctly as far as I can tell. Using -v/-vv/-vvv makes no difference. Thanks for any help. Phil

Thanks to gfjardim for creating the CUPS docker! I’m trying to get it working with a brother HL1210W printer. I have downloaded the CUPS .deb driver package from the brother website and placed this into the CUPS/brother/ folder. The printer itself is on my network wirelessly. I know the IP and have put the following network path into CUPS: lpd://internalIP/binary_p1 I have then selected the HL1210W CUPS driver which appears as a result of me having downloaded the driver file - note the printer name appears twice in the driver list for some reason. Selecting either of these does not work. This is as described on the brother website on how to configure the printer for use with CUPS. On trying to print a test page I get a ‘filter failed’ error. I can’t determine what is causing this as I seem to have followed all the instructions! To test this, I have tried running with one of the other brother drivers (HL2140). When printing the test page with this driver selected it sends the test page, the printer light blinks 3 times, nothing comes out and the job is marked as ‘Completed’ in CUPS. Any help gratefully received! Thanks, Phil

Update on my own questions: 1) the DEBG log entries calm down after the docker has been open a while. Nothing I can see that I've done so I think maybe it's to do with initialisation and loading of all shows on iplayer into the get_iplayer database. 2) Using midnight commander through ssh I can navigate to the incomplete folder and the files all have the correct names. It appears the issue arises because the show name has a colon in it which Linux is happy with but windows is not. If I change the show name in the docket cofig to not include the colon it doesn't pick up the show. The files are still not being moved to the complete folder however, not sure if this is because of the same colon issue? If anyone has any insights I'd appreciate it! Cheers, Phil

Hi all, and thanks binhex for the container! Couple of questions: 1) in my get_iplayer docker log I'm getting the following output about 4 times a second: 2017-01-24 08:57:40,711 DEBG 'get-iplayer' stderr output: Is this normal behaviour or have I got a setting wrong? 2) Regarding show downloads, I have a show set to download and it seems to be pulling the shows down correctly to /data/get_iplayer/incomplete/ folder as .flv files then converting to mp4. At this point the files are not being moved to /data/complete The files are left in the incomplete folder with random text strings as the name (possibly the episode ID?) Because of the log file filling so quickly it's hard for me to debug on the fly! Any help much appreciated! Thanks again, PhilUK

OK, So since my last post I've done a few more changes to the array and rooted out the cause of the behaviour if not the root cause of the actual issue. I removed the Sandisk 128GB cache drive from the pool following the instructions in the user manual. After this, the speed of the cache drive is back to expected levels. Therefore I conclude that the problem is arising from: 1) Issues with TRIM which I cannot run/solve using the BR10i controller 2) Issues with the cache pool itself resulting in write issues? 3) An issue with the sandisk 128GB SSD - to be confirmed by adding to the array and running write tests Has anyone else had/seen issues with cache pools and timeouts/speed drops during writes?

Hi Rob, I've run the scrub command to no effect sadly. I will definitely consider breaking the pool and rebuilding. Maybe worth waiting to see if I can resolve any TRIM issues. SMART reports look OK, one of the drives has a single reallocated sector. I checked this when it was first added to the array and it appears to be common for there to be reallocated sectors with the model I'm using (Sandisk SSD). The rellocated sector count has been stable since it was added to the array (6 months+). The other drive is all green w.r.t. SMART. I get this report back when trying to run that command. Is this indicative of an issue? fstrim: /mnt/cache: the discard operation is not supported Thanks, Phil

OK, So I've run hdparm -Tt on each drive with the following results: /dev/sde: (Cache Drive 1) Timing cached reads: 11508 MB in 2.00 seconds = 5757.43 MB/sec Timing buffered disk reads: 796 MB in 3.00 seconds = 265.13 MB/sec root@Tower:~# hdparm -Tt /dev/sdf /dev/sdf: (Cache Drive 2) Timing cached reads: 7742 MB in 2.00 seconds = 3872.25 MB/sec Timing buffered disk reads: 760 MB in 3.00 seconds = 253.07 MB/sec root@Tower:~# hdparm -Tt /dev/sdg /dev/sdh: (240GB SSD On Same Controller - disk3 below) Timing cached reads: 11544 MB in 2.00 seconds = 5775.54 MB/sec Timing buffered disk reads: 730 MB in 3.00 seconds = 243.12 MB/sec So read speeds look OK (over a 3 second period). Just run the write_speed_test.sh to write the 10GB file to: /mnt/cache - cache pool of 2 x 128GB drives on BR10i /mnt/disk3 - 240GB SSD on same BR10i as cache drives /mnt/disk4 - WD RED 3TB on motherboard controller Results were: Write to /mnt/cache took 13.5 mins (12.6MB/s) with multiple periods where either slowdowns or hanging of data writing occured - e.g. stuck at 9.0GB written for >60s. Write to /mnt/disk4 took 6 minutes (28.3MB/s) - constant speed Write to /mnt/disk 3 took 5m 40s (30.1MB/s) - constant speed So definitely a problem somewhere with the cache pool. How do I now start to work out the cause of the problem? NB: I have attached diagnostic zips to this post. EDIT: I ran another few runs using write_speed_test.sh and copied the output from the terminal into excel and plotted the write speeds (both the speed reported by dd as well as a value I calculated manually from the terminal data) over time. I have attached these as an image and it's pretty telling and confirms a problem in the cache pool. Thanks, Phil tower-diagnostics-20160518-2029.zip

Can someone help with the commands to check read and write speeds on each drive please? I've seen them used in other threads but can't find it! Thanks, Phil

Agree with this, Crashplan is great, I have a friend with an unraid server. We both back up super-critical items to each others servers using crashplan. Benefit with that is that it's free! $60/year you get unlimited cloud backup with it too although never used that option. Phil

Hi all, Looking for some help on an issue I have now seen across both an N54L and Gen8 microserver. When copying files to the array from a windows PC connected via Gigabit ethernet the writes will start at 100MB/s then drop down to almost 0MB/s then jump to between 5 and 15MB/s. The drop outs then cycle every 20 seconds or so until the file is fully transferred. Trying to decipher the issue, I used ftp via Filezilla from the same PC. Transferring to the /mnt/user/ folder I get the same behaviour. The writes start very fast then drop to almost nothing with time-outs occurring intermittently. However, transferring direct to the target disk or to /mnt/user0, the transfers start at 100MB/s then continue at around 25MB/s to the end of the transfer with no hangs. As such, I believe the issue is coming from the cache pool. I confirmed this by writing direct to /mnt/cache and saw the hanging behaviour again. The log for unraid (accessed via the GUI) shows no errors. Both cache drives are connected to a BR10i configured in IT mode via LSI firmware (as described elsewhere on this forum). Both drives are connected to the same miniSAS --> 4 x Sata connector. Could there be a bottleneck here? I would expect to see low speeds and not hangs if this were the case? I guess the other option is potentially a failing drive? Can someone help me to work out the issue? At the moment I'm tempted to disable the cache as it's making the array almost unusable due to the hanging behaviour. Thanks in advance, Phil

Perfect thanks! Strange behaviour from mc that it waits until the end of the move command to delete the source files? I would have expected it to remove from the source once the individual file had moved as it goes along. Never mind, I've learnt something new. Thanks both! Phil

Hi all, Hoping for some help here. I'm about to upgrade a drive on my server and went to use mc through putty to move all the files off the disk (disk5) to another disk (disk2). When moving the files every single file is duplicated on disk2. Is this normal behaviour? I have not done this on purpose to my knowledge! I've not yet deleted the files from disk 2 in case something odd is going on... I've got 2 questions really: a) Is there a way to detect duplicate files on the server? b) And how can I be sure the files are not going to be lost when indexers them from disk 2? Thanks in advance! Phil

Providing a one time app code in Gmail definitely works as this is the way I have plexReport set up. This is a great docker ninthwalker, working perfectly to send out updates to family after a bit of trial and error with config.yaml! Do you have any plans to introduce a GUI for this? Cheers, Phil

Are there any plans following release of 5.0 to look at the license structure? I'm going to be on the cusp of a plus/pro license (8 drives) once I populate my server and would be great to know what is planned before I take the plunge! Cheers, Phil

Have given up on this and purchased a BR10i instead which I can flash to IT firmware. If anyone ever works this out then let me know! Might be a bargain 8078ELP on eBay soon Cheers, Phil

I have used megacli to run the following command as stated in the thread above: MegaCli -CfgEachDskRaid0 -aAll This sets the drives in the following configuration: Virtual Disk 1 - Physical Disk 1 in Raid 0 Virtual Disk 2 - Physical Disk 2 in Raid 0 Unfortunately this card cannot just pass through the disks to be directly controlled by unRaid like the LSI1068 or 2008 based cards. They have to be controlled by the card so this is as close as it can get to JBOD as far as I can tell. The virtual disks show up in Windows if I connect the card and disks to my other PC. They just don't seem to be detected in unRAID. Any further ideas? Cheers, Phil

Hi all, I recently managed to get an LSI 8078ELP card and am having issues getting any kind of disk to appear in unRAID 5.0rc15a no matter what configuration I set up. I have both drives attached to the controller set up as individual virtual disks in RAID 0. This controller does not support IT mode firmware so the disk has to be run in IR mode in this way as far as I can tell? The post here: http://lime-technology.com/forum/index.php?topic=9950.msg116635#msg116635 suggests the driver required to run this card is not included in unRAID (any more or has never been I'm not sure). Is there anything I can do to get this card to play nicely with unRAID or am I barking up the wrong tree here trying to mess around with a card with this chipset? I have attached a syslog which I think just shows that the drives are not being detected by unRAID at all. Thanks for any help! Phil 2013.07.27_-_unRAID_syslog.txt

Hi All, Just got my hands on an LSI 8078ELP card using the 1078 chipset. What are my options with this & unraid? Cheers, Phil
