December 10, 20232 yr I'm running unraid 6.12.4. This is likely not unRaid specific, but I don't know. TLDR: I can mount a LUKS drive but sometimes when on luksClose it won't close, but so far waiting 15 minutes helps. I tried creating a LUKS encrypted file using this guide: https://blog.tian.it/create-encrypted-luks-sparse-file/ When I unmount the mounted filesystem and then try to close the LUKS using ``` umount /cryptoarchive/stuff cryptsetup luksClose "/dev/mapper/stuff" ``` then I get the following error: ``` Device /dev/mapper/stuff.img is still in use. ``` Running `df` I can see the unmount worked, and also the `umount` didn't fail. `lsof` shows me that the loop-device file is (of cause) still in use, but no files on the mounted dir `/cryptoarchive/stuff` is shown . Once after waiting an hour or so, I tried remounting and then umounting immediately afterwards, and that one time luksClose succeeded. I have shared the mount point via samba, but as mentioned umount works. I have attached my mount and unmount scripts. Thx, Alex luks-unmount.sh luks-mount.sh Edited December 10, 20232 yr by Alex R.
