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).

I created a bug report:

Hi, Since I upgraded from UNRAID 6.10.X et 6.11.X, I cannot edit anymore shares with a 'dot' in their name. When I hit "apply", a popup appears in the GUI saying that "hidden shares are not allowed". I emphasise that the name of the share is "domains.appdata", and does not begin with a 'dot'. Is that intended behaviour ? Why would a dot in the middle of the name of a share make it a "hidden share" ? Many thanks,

Hi all, I have an OpenVPN server running on my Unraid 6.11.5 system. OpenVPN is using the 172.16.92.32/28 CIDR and my Unraid server's local IP address is 192.168.92.100. (on the 192.168.92.0/24 CIDR) I would like Unraid to masquerade packets coming out from the OpenVPN clients, so I added the following in the IP tables: iptables -t nat -A POSTROUTING -s 172.16.92.32/28 -o br0 -j MASQUERADE However, when I set a machine to capture packets incoming from the OpenVPN clients, they are still showing as coming from the IP 172.16.92.34, and not from 192.168.92.100. Do you know why ? Many thanks, OP PS: I know I can add a route in my router to achieve a similar result but I want to have the option of not having a "prosumer" configurable router.

Thank you @JorgeB. My array is encrypted so clicking the button result in a "Missing encryption key" error, as no field is available to enter the passphrase. I rebooted the server once again and the START/STOP buttons are now showing, along with the passphrase field. Very weird indeed I wish you a good day. OP

Hi all, After a server crash I performed a parity check and rebooted. Now I cannot start my array. The button is not even shown in the WEBGUI (see attached screenshot). I also noticed strange errors on the Docker page: Warning: stream_socket_client(): unable to connect to unix:///var/run/docker.sock (No such file or directory) in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 712 Couldn't create socket: [2] No such file or directory Warning: Invalid argument supplied for foreach() in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 898 Attached are my diagnostics files. Many thanks for your help. With regards, OP

I confirm that new version 2023.02.11 seems to work again. Is there a way to recover files deleted while the version 2023.02.10 (the one with the bug) was running on my system ?

Many thanks. The NVME drive is showing back after a power cycle. I will now see if the problem happens again. I wish you a very nice day. OP

Hi @JorgeB, Thank you so much. While I was waiting, I restarted (without making the change you suggest) and now my NVME drive is shown as "missing" by unraid. Would that be still useful to try and perform the changes to the syslinux config that you suggest ? FYI mine is as follows: default menu.c32 menu title Lime Technology, Inc. prompt 0 timeout 50 label Unraid OS menu default kernel /bzimage append pcie_acs_override=downstream initrd=/bzroot label Unraid OS GUI Mode kernel /bzimage append pcie_acs_override=downstream initrd=/bzroot,/bzroot-gui label Unraid OS Safe Mode (no plugins, no GUI) kernel /bzimage append initrd=/bzroot unraidsafemode label Unraid OS GUI Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot,/bzroot-gui unraidsafemode label Memtest86+ kernel /memtest Thank you very much. OP

Hi all I just saw that my log were filled with errors mentioning BTRFS. I am bit lost and hope someone could help me identify the problem. The NVME drive is using XFS and is set as "cache", and I have 2 SATA SSDs using BTRFS set up as a separate cache "sata-raid" pool. Note that for now, TRIM fails on the 2 SATA SSDs because my HBA card does not support it. Below are the first occurrences of the errors. The diagnostics files are also attached. Thank you so much for you help.

I checked all commands of https://wiki.unraid.net/Console#Console_Commands_for_Hard_Drives as well as the lsblk command, but without any success.

After updating to Unraid 6.11.5, I finally get the same results as you: I was able to start the array in maintenance mode after deleting only the LUKS keys. I was able to wipe the LUKS header completely with "wipefs -a /dev/md1" (but I had to restart the array in maintenance mode). I was able to restore the LUKS header on /dev/mdX (i.e. with the array started in maintenance mode) I did not get any error after a performing a parity check after all that. I opened a new thread here to get additional help regarding how to obtain the SERIAL_ID of the disk hosting a certain dev/mdX managed partition.

Hi @itimpi, many thanks. I did indeed test that with @Kilrah in this thread, and the results are inconsistent. With the LUKS key missing on one drive, the array can start on @Kilrah's system, bit on mine the array fails to start. However, with the LUKS header completely removed (not just the key), it seems that I can start the array.

Hi all, How can I identify, via command line, which /dev/sdX1 partition corresponds to the /dev/mdYp1 managed partition? The info is on the WebGUI main page but I need to get that info in the context of a script. Many thanks. OP

I tried on my system and had parity errors...: root@BEETHOVEN:/boot/luks# cryptsetup erase /dev/md1 WARNING! ======== This operation will erase all keyslots on device /dev/md1.

Likewise.

On my former test I used "cryptsetup erase /dev/sdx1". So I did like you: array started in normal mode run backup script cryptsetup erase /dev/md1 (variation in my testing) stop array reboot (new step in my testing) > the array fails to start, as with "cryptsetup erase /dev/sdx1" Our results are clearly different.. FYI I use Unraid 6.9.2 on my testing VM.
