Hi there,
I recently changed my cache drive from btrfs to zfs, and now when I try and stop the array, it gets stuck trying to unmount the disk shares.
If I try and shutdown the array, it has to force a shutdown.
I have this in the syslog:
Jul 12 20:10:33 Percy emhttpd: Unmounting disks... Jul 12 20:10:33 Percy emhttpd: shcmd (267285): /usr/sbin/zpool export cache Jul 12 20:10:33 Percy root: cannot unmount '/mnt/cache/appdata': pool or dataset is busy Jul 12 20:10:33 Percy emhttpd: shcmd (267285): exit status: 1 Jul 12 20:10:33 Percy emhttpd: Retry unmounting disk share(s)...
Diagnostics from a previous force shutdown are attached (I have two others - one earlier, and one just now - that I can add too, if need be).
I have my Dockers mapped to disk shares (including /mnt/cache/appdata/) for performance purposes, so am unsure if it's related to using disk shares rather than the user share.
Your help is appreciated.
