I've been lazy and not upgraded for a long time now, figure I ought to but searching around here seems to suggest there are certain recommended steps and procedures to take, e.g. upgrading to specific key versions along the way and carrying out particular procedures as I go. Does anyone have any definitive info given the starting point of 6.3.5? Is there a more bulletproof backup procedure for the flash drive before I start (e.g. taking a full image of the whole thing) or is copying all the files on the /flash share good enough?

ok thanks I'll give it a try...

Fair enough, but it still won't solve the problem of losing the mount during sleep/resume will it?

I have my unraid server automatically sleeping when all the disks are idle. I quite often have a USB drive connected and mounted, but the mount is no longer functioning after resuming the system. The mount is still listed in the output of the mount command, but it can been seen from the device list that the USB drive is listed as a different device to the one originally mounted. To re-mount I have to umount and then mount again using the new device name. After a further sleep/resume, the same happens except its gone back to the original device name. e.g. /dev/sdh1 is mounted, after sleep/resume the device is /dev/sdi instead, and the original mount no longer works. If I umount /dev/sdh1 and mount /dev/sdi1, after a further sleep/resume, it goes back to /dev/sdh. Is there a way to stop this happening without umounting this drive before sleeping?

Great, thanks again!

Thanks! Rebuild is in progress now but I'll change the cable after and keep an eye on the CRC error count for a while. Out of interest does Unraid care if I move the drive to a different SATA port (might try this if the CRC error count keeps increasing after changing the cable).

Last night I powered off my unraid server to reconnect an SSD drive (an old Windows OS drive), which I needed to copy some data from. When I started up again I also connected a USB hard drive to copy the data to. I completed what I needed to do successfully and unmounted these drives. About 15 minutes later the following errors occurred (I actually didn't notice the problem until today but am looking at the logs etc now). I believe the array was being written to at the time (almost certainly not disk1 though): Dec 22 22:56:47 Tower ntfs-3g[9507]: Unmounting /dev/sdc1 (Work) Dec 22 23:15:27 Tower kernel: ata6.00: exception Emask 0x10 SAct 0x0 SErr 0x280100 action 0x6 frozen Dec 22 23:15:27 Tower kernel: ata6.00: irq_stat 0x08000000, interface fatal error Dec 22 23:15:27 Tower kernel: ata6: SError: { UnrecovData 10B8B BadCRC } Dec 22 23:15:27 Tower kernel: ata6.00: failed command: READ DMA EXT Dec 22 23:15:27 Tower kernel: ata6.00: cmd 25/00:00:e0:66:c4/00:04:7d:00:00/e0 tag 0 dma 524288 in Dec 22 23:15:27 Tower kernel: res 50/00:00:df:66:c4/00:00:7d:00:00/e0 Emask 0x10 (ATA bus error) Dec 22 23:15:27 Tower kernel: ata6.00: status: { DRDY } Dec 22 23:15:27 Tower kernel: ata6: hard resetting link (repeats several times) ...

This carries on until 23:30, but then nothing happens until around 3am when unraid decides the disk needs to disabled, then it e-mails me at 03:47. I've since stopped the array, noting that the disk had disappeared. Shutdown, disconnected the SSD I had connected last night and checked all the SATA connections. Powered up again and the disk is visible again, but still red. I've attached a SMART report along with the syslog. I assume I need to do the un-assign, start, stop, reassign procedure regardless, but do the errors in the logs suggest a SATA hardware issue or dodgy connection, or that the disk is on the way out? All seems a bit co-incidental with me connecting another drive, so hopefully the disk is not toast? unraid_syslog-2014-12-23.txt smartctl.txt

Looks like it is. Thanks very much!

... But with front loading access. Well I don't mind hot swap but they're too expensive (looking for under £40), so there must be some cages don't require removal of the whole cage just to replace a drive?

Mostly will be streaming to a Chromecast which as I understand it requires transcoding for almost everything. Looking at a quad Q6600 now as its only £27, better bang for buck ratio!

I'm running 5 at the moment. I guess I'll want to upgrade to 6 in the near future though. Well there isn't a fixed amount of spare cash to spend on this. If I come to the conclusion to build a new system, I won't scrimp on anything, it will just be a slower process, buying the bits as I can afford them. I'd still be looking to spend as little as possible to get the job done though. It's basically comparing the cost of getting a new CPU & RAM vs the cost of a new mITX board (so I can move it to a smaller case later), CPU and RAM to meet the requirements set out. If there isn't that much in it I might as well replace the motherboard, but if the simple upgrade is much cheaper and won't disadvantage me for the next couple of years I'll stick with that idea. I know I can work out these costs myself, I can use your thread as a basic idea of the new build cost (though I am in the UK so this also has an impact), so I've got a bit of research to do. Does anyone know the answer to the Windows VM question above? I do need to use this computer as an ordinary Windows machine occasionally (not for games, but simple photo editing at least). If its going to be impossible to do this all on one system, then I know I have to build a new one specifically for unraid.

I have an old tower PC with 4 hard drives and an SSD which acts as a "fileserver" running Windows 7. I experimented with SnapRAID briefly, but have been trying out Unraid for the last 2 months. I definitely want to continue with Unraid so I've bought the Pro licence and the 4 drives are now all part of the array (the SSD still has Windows on it, so I can dual boot). The next stage of my plan was to build a new system (probably Lian-Li Q25B based) for unraid and move the drives across, freeing up my Windows system for the occasional use I had before and enabling unraid to run 24x7. However, budget's a bit tight now so am looking at the possibility of sticking with the current setup, but with upgrades to support: - Plex media server (single 1080p stream is fine). - A VM running Windows 7, hosted on unraid. I'd like to be able to use the Windows install running on this VM with my existing monitors, keyboard mouse, if that makes sense and is even possible?? (haven't played with VMs for a while) rather than having to remote desktop from another machine (which I don't have!). Probably wouldn't have the VM running all the time... The current hardware setup is: - Antec Sonata Piano black case. Ok its old, but I can use pretty much any motherboard/PSU setup I like and it has 3 x 5 1/4 inch bays so I would plan to buy a hot swap cage for this space (that still leaves 4 standard 3.5 internal bays). - Asus P5QL-EM mobo (socket LGA-775, 6 SATA ports). - Pentium E5200 (I could upgrade this to a 2nd hand Core2 Duo E8500 very cheaply via ebay - this should cope with the Plex requirement?) - Elan Vital Greenerger SSM PSU 400W. Great when I bought it, that was almost 9 years ago! Very quiet but its not dual rail... probably could get more efficient PSU these days? - 4GB - would upgrade to 8GB or maybe even 16GB I do want to reduce power consumption (~50W idle currently) since its on 24x7 now, but also realise that's probably unrealistic without swapping out at least the PSU, mobo and CPU (only thing missing then is a new case anyway!). So any thoughts?

Oh yes, thanks. Think I'll continue and just keep an eye on it

Hi, I'm about to add an old 500GB WD drive to my array. Although preclear passes and indicates no re-allocated sectors, there are some SMART errors reported that I'm not sure how to interpret. Can anyone suggest if the drive is "safe" to use? I've attached the full report and finish logs, but here are some of the lines of concern: SMART Error Log Version: 1 ATA Error Count: 89 (device log contains only the most recent five errors) Error 89 occurred at disk power-on lifetime: 2254 hours (93 days + 22 hours) Error: UNC 8 sectors at LBA = 0x00deaa87 = 14592647 Error 88 occurred at disk power-on lifetime: 2254 hours (93 days + 22 hours) Error: UNC 128 sectors at LBA = 0x00deaa77 = 14592631 I can't even work out if 2254 hours was a long time ago or recently...
