January 22, 20242 yr Recently, I had a need to stop my unraid array to make some settings changes. After a couple of hours, it was still saying that it was trying to stop the array. I noticed in the lower left-hand corner, the status kept saying " Array Stopping•Retry unmounting disk share(s)". I rebooted the system, but I am having the same issue as i can't stop the array. I have attached a diagnostics dump and would appreciate any help. v/r Jon unraid-1-diagnostics-20240122-1419.zip
January 22, 20242 yr Your cach disk is staying busy: Jan 22 14:06:48 Unraid-1 emhttpd: shcmd (237): /usr/sbin/zpool export cache Jan 22 14:06:48 Unraid-1 root: cannot unmount '/mnt/cache/system': pool or dataset is busy Jan 22 14:06:48 Unraid-1 emhttpd: shcmd (237): exit status: 1 Jan 22 14:06:48 Unraid-1 emhttpd: shcmd (238): /usr/sbin/zpool export cachemirror Jan 22 14:06:49 Unraid-1 emhttpd: shcmd (239): rmdir /mnt/cachemirror Think about what is on your cache. Things like the Docker Image? Appdata? Something is keeping it busy. Boot in safe mode and see if you can stop the array. Add things back a little at a time until it breaks to find which part of your system is keeping the cache busy.
January 23, 20242 yr Community Expert Solution Jan 22 14:06:28 Unraid-1 emhttpd: shcmd (205): umount /var/lib/docker Jan 22 14:06:28 Unraid-1 root: umount: /var/lib/docker: target is busy. Looks like docker image not unmounting is the main issue, re-test with v6.12.7 once it's out.
January 23, 20242 yr Author Thanks @JorgeB. I let it sit all night and this morning I was able to get the array to stop. I made my change (tried to join it to my MS AD test domain (didn't work)), and then tried to start the array. Now, it appears to be stuck at "starting services". It has been this way for several hours now. If it helps, I have attached a new diagnostics dump. unraid-1-diagnostics-20240123-1040.zip

January 23, 20242 yr Author Will do... is there a best practices document for joining an UNRAID server to a Microsoft Active Directory Domain? I have not had any luck in doing so.
January 23, 20242 yr Community Expert I believe there are some known issues with AD and the current releases, you can try this:
January 23, 20242 yr Author @JorgeB thanks for the suggestion. I have tried these as well, but with no luck. I'll keep trying.
