I am using ZFS mostly on my USB attached HDD.
One of disks disconnected (USB fault) and my entire machine is hung on I/O.
This means that I can still use the shell (where I am almost all the time)...unless is something that have to access the I/O subsystem, which makes the session to hung.
I already had few iTerm sessions open to helpmeet identify the culprit, and seems that it is the ZFS.
Facts I have at this stage:
- iMac Intel running Sierra (see below)
- ZFS installed three weeks ago
- zpool list, pool iostat, pool status is showing information, which I cannot copy/paste because I am using second computer. The computer experiencing the problem cannot be used for any activity that relies on disk access
- sudo pool clear hangs the session
- Disk affected is /dev/disk9 vol201. Turning it off does not make any difference. Turning it on back still any difference
- Only solution, at this point, is to reset the computer...again
Any ideas?
- Code: Select all
