It actually works.

I would be very happy to know if limiting write speed to array is possible. Any news by any chance ?

FYI, I found in a comment under one of SpaceInvaderOne's video on YouTube that someone figured out how to finalise the "stop array" operation when this problem occurs : (link to source - see the "highlight reply" below the video) I hope this workaround will help until, hopefully, this issue is fixed.

I rebooted and got an unclean shutdown... Now performing a parity check... I later found a comment under one of SpaceInvaderOne's video on YouTube that someone figured out how to finalise the "stop array" operation (https://www.youtube.com/watch?v=nV5snitWrBk&lc=Ugweuc_wFZta3uxs0PV4AaABAg.9u9MWHF1ArU9vHBCZfLE09) : I hope this will help.

I mean "was" encrypted, now it is filled with zero. I thought about mounting the drive manually to unlock the "not mounted" error loop but I think that is not possible now the drive has no file system on it.

Hi, i am currently facing that problem during a critical shrink array operation: Have you been able to find a solution to complete the stop array operation properly ? I was thinking about mounting the drive manually via CLI, to see if that would fix that error but I am unsure whether this is a good idea.

I should point out that disk10 is encrypted.

Hi, I have just finished zeroing disk10 using this script, during the course of a "shrink array while retaining parity" operation. I understand that this script unmounted disk10 just before zeroying it, as shown in the log below: Unmounting Disk 10 ... Clearing Disk 10 ... I now need to stop the array to create the new config without disk10, but i am stuck with this status: retry unmounting disk share(s) Unraid logs show the following, which seems coherent with the unmounting performed by the zeroying script: Nov 3 15:39:18 MOZART root: umount: /mnt/disk10: not mounted. Nov 3 15:39:18 MOZART emhttpd: shcmd (17681057): exit status: 32 Nov 3 15:39:18 MOZART emhttpd: Retry unmounting disk share(s)... How can i complete the "stop array" operation ? I really need to do it the clean way this time. Attached are the diagnostics files, if required. Many thanks, Op

Indeed. I cannot remember why I came to that conclusion. Many thanks !

Hi, How can I start and stop syslog server from the command line ? (I have been looking for a long time but cannot find the answer) My Unraid machine is the syslog server for my network I want to be able to perform proper backups of the logs, which I cannot do if the syslog server is running apparently. Many thanks, OP

Have you been able to get the OpenVPN server working with any package sourced from the official slackware website ?

Noted. The disk is on a backplate connected to an HBA with SAS cables, so I kinda ruled out the cable issue (although I will order an extra cable to make the swap as you suggest). But the disk having been on 24/7 for more than 10 years, I think its time for replacement indeed. If the issue persists after I have put a new disk, then it means this slot of my HDD backplate is defective (which would suck...)

UPDATE: Data rebuild finished successfully (I think) but the parity check performed right after caused new read errors. As I still have 31 TB of free space available on my array, I have decided to scatter the 350GB of data from the failing drive (currently emulated thanks to parity) on another drive, then perform a shrink of the array (I will try the method that preserves parity first) and then dispose of the failing drive. Do not hesitate to let me know if I am making a mistake 🙂. In particular, I wonder if I should zero the failed drive while it is being emulated, or actually zero the drive after reassigning it in the config. Unless it makes no difference (which I think could be the case) ?

This is noted. Thank you very much for your help.

Since the drive looks fine, I took the chance of initiating a rebuild onto itself, as shown here: https://docs.unraid.net/unraid-os/manual/storage-management/#rebuilding-a-drive-onto-itself

The extended test completed without error (see attached).

Hi, I just got HDD read errors this morning on my drive nb 9. What is your advice regarding that disk and the others ? Bellow is an abstract of the SMART info for that HDD (WDC_WD40EFRX-68WT0N0_WD-WCC4E2DCKH26-20231004-1912 sds), and attached my diagnostics file.

I confirm that @naturalcarr's workaround works fine, except for the "COMMAND" parameter which I changed as shown below to avoid files permissions being changed, and changing permissions for folders only. WATCH_DIR=/dir1 SETTLE_DURATION=5 MAX_WAIT_TIME=05:00 MIN_PERIOD=00:01 COMMAND="find ${WATCH_DIR} -type d -print0 |xargs -0 chmod -c 777" USER_ID=0 GROUP_ID=0 UMASK=0000 IGNORE_EVENTS_WHILE_COMMAND_IS_RUNNING=1 USE_POLLING=no DEBUG=0 Regarding the permissions for the files, they can be set within the metube container itself, by adding the following to its options: "postprocessors": [{"key": "Exec", "exec_cmd": "chmod 0666", "when": "after_move"}] Also, for those who are wondering, the above inotify-command parameters works with the inotify-command docker container available in the Unraid apps.

Please, do it -

It would be awesome if that issue could be fixed... Folders created by YT-DLP needs to have 777 permissions. This causes a lot of issues (like the "bin button" not working in the GUI for example).

Yes, zeros. You could replace "/dev/zero" with "/dev/random" to have randomised data (subject to the warning bellow). This link can help you decide which one to pick: https://stackoverflow.com/questions/11499409/dev-zero-or-dev-random-what-is-more-secure-and-why I guess the safer way for you might just be run the script "X" number of times. Playing with the "dd" command while not being comfortable with the CLI can result in loosing all your data (I am not kidding).

Hi @bonienl - Thanks ! Op.

I created a bug report:

Personally, I did, and the screen showed nothing in particular. Maybe someone else will have some more luck. @Tristankin, Do you happen to have multiple NICs on you motherboard by any chance ? I ask because I have the same problems as you, and it seems I may have regain stability (30 days uptime and still no crash) by disabling my BR1 network interface (which I used for VMs on a separated vlan), leaving only BR0 enabled. I know it seems very random and unrelated, but without anything useful in the logs (like you) I just try random things now...
