I'm interested in DSD support as well. binhex, would it be possible to include the file modifications described in this thread?

Thank you, I look forward to trying this. I seem to remember it was not possible to automatically re-start the HDHomerun DVR engine when the unRAID server was rebooted. Is that no longer a problem or is there a workaround?

Yes I noticed this as well.

My latest preclear of a Western Digital 8 TB WDC_WD80EFAX got stuck at post read 94% I'm using Preclear Disks 2017.07.10, Unassigned Devices 2017.07.09c and unRAID 6.3.5 Attached are the logs. I had a similar failure with a WD 8TB Parity WDC_WD80EFZX using an earlier version of the plugin. I noted back in July that based on several similar posts the WDC_WD80 seemed problematic with the preclear plugin. I don't know if there have been any posts noting success with the plugin and these drives since. My last successfull preclear was on a Seagate Archive 8 TB ST8000AS0002 using Preclear Disks 2017.07.05c, Unassigned Devices 2017.07.04a and unRAID 6.3.3 Also please note the below previous recent posts reporting similar behavior with HGST 4TB and 8TB as well as a Hitachi HDS5C4040ALE630 4TB. 13-AUG-2017 Vibe HGST 4TB 13-AUG-2017 JarDo Hitachi HDS5C4040ALE630 4TB 16-AUG-2017 bbcorn88 8TB HGST raid_01-diagnostics-20170830-0912.zip RAID_01-preclear.disk-20170830-0859.zip

Did you have any success with subsequent attempts on your new drive or HGST 4TB drives using the plugin with default gfjardim-0.8.9-beta script? What about with a modified script run from the command line? One thing that would be hugely helpful is posting with any modified working preclear scripts that can be run from the command line in unRAID v6. Thanks!

Sorry, at the time of the problem CALCULATE run I did not know to look for the log and have since successfully run CALCULATE. For what it's worth, attached is my latest unbalance.log from a successful run after fixing some permissions on my disabled disk 3 per the OPERATION FEEDBACK screen. Also attached are screenshots from the successful run of CALCULATE with the OPERATION FEEDBACK and the run after fixing the permissions. I wanted to avoid any kind of system wide newperms run so ran it manually from an ssh session with newperms /mnt/disk3 After doing that I now seem to be getting a 'clean' CALCULATE with no orange OPERATION FEEDBACK screen. One thing I don't understand is in the unbalance.log after running newperms /mnt/disk3 it still seems to be showing a (group?) [dabl] for some files but when I look at those via ssh ls -l it shows the group as 'users'. Maybe I'm just confused on that. EDIT: also attaching the unbalance.log generated during the run with the OPERATION FEEDBACK screen since I had saved that one. EDIT: Hmm comparing the .log files I see the second run just got appended so that was probably uneccessary (duh) Also what I was seeing with the [dabl] group was actually from the first run and was NOT in the second run...... unbalance.log unbalance log from CALCULATE results OPERATION FEEDBACK .log

Thanks, that's what I figured but for whatever reason when click the CALCULATE button nothing is happening except the CALCULATE button then as expected becomes disabled. I get no console as shown in the doc. Nothing shows in the Log page and the REFRESH button on that page is disabled. Attached is a screenshot. The reason I want to do this is I was headed down the path of converting my reiserfs drives to xfs using a new empty 8 TB drive. The disk 3 that just became disabled is 1.5 TB and I have space available on the 8 TB disk 8. The 8 TB disk 9 is my new empty drive. I'd prefer not to have to rebuild the 1.5 TB reiserfs disk 3 using disk 9 but perhaps that is the best thing to do at this point and then move the data to disk 8 and start the reiserfs to xfs conversion again. To complicate matters disk 6 was showing signs of going bad so I moved the data off that disk using the krusader docker. Disk 6 is now empty and I would like to take it out of service so things don't become even worse if/when disk 6 gets disabled, right in the middle of a move operation for example. I'm open to any/all suggested approaches. EDIT, UPDATE: I turned notifications on and restarted the plugin and am now seeing the console on CALCULATE and output on the Log page so the plugin does appear to at least be working for me now. Am still interested in general input on suggested approaches to my situation.

Is it possible to use this plugin to move files from a disabled disk to a good disk?

Maybe an obvious/not particularly useful observation but it seems there is something about the WD Reds that give the current preclear routine(s)/and or plugin fits. I had the same kind of failures with one of those with an earlier version of the plugin (almost makes it to the end then stalls). The last disk I tried, a Seagate Archive precleared successfully. I wonder if running the one of the preclear routines standalone/independent of the plugin would yield different results. Obviously it is time consuming and frustrating to test this kind of failure.

I wanted to report a successful preclear with the below. I did not see any unexpected behavior. The preclear was started before the latest updates. Thank you to gfjardim and dlandon for these plugins. ====================== Seagate Archive 8 TB ST8000AS0002 Preclear Disks 2017.07.05c Unassigned Devices 2017.07.04a unRAID 6.3.3

Is this fixed in 6.3.2?

Thanks Rob for the fast reply and great info, greatly appreciated. I will definitely take note of this for future use of Seagate drives with preclear/smartctl.

Thanks for any comments on what look like high numbers to me for the Raw_Read_Error_Rate, Seek_Error_Rate and Hardware_ECC_Recovered compared to other drives I have including a recent WD 6TB Red. I know Reallocated_Sector_Ct and Current_Pending_Sector are key values to check and those look ok. This is one of the newer Seagate 8TB drives cleared using the Unofficial Faster Preclear I want to use this drive as part of a parity swap procedure including a failed drive. Just to be clear I'm familiar with that procedure.

Thank you for taking the time to do this, extremely helpful!

How does one check periodically/on demand etc for the latest firmware to flash an IBM ServeRAID M1015 to LSI MegaRAID SAS2008 please?

Thanks for these scripts. Is there any possibility at some point for such a script be able to tell if a fan has failed and then possibly make use of smtp capability to email that to a user?

New version of preclear_disk.sh does log the difference to the syslog. There was no good reason not to, just did not think of it until you mentioned it. Thanks for the suggestion. New 0.9.6 version has a few other improvements in reporting via e-mail (if you have a mail program configured on your server) and also reports drive temperature as the process is under way (in case the drive is overheating from lack of cooling air movement) New version is attached to first post on original thread here Joe L. Awesome, thanks very much!

Cool, that would be a good thing to add to the post
