[OmniOS-discuss] 8TB Seagates under load = PANIC?

>> What's pool5/fs1's actual mount point?  (
root at zns2-n2:/var/adm# zfs get mountpoint pool5/fs1
NAME       PROPERTY    VALUE       SOURCE
pool5/fs1  mountpoint  /pool5/fs1  local

>> Does that directory contain something?
root at zns2-n2:/var/adm# ls -la /pool5/fs1/
total 1
drwxr-xr-x 2 root root 2 Mar 16 14:39 .
drwxr-xr-x 4 root root 4 Mar 17 05:55 ..


And I also try to mount it to another location, but I can't do that

root at zns2-n2:/var/adm# zfs set mountpoint=/pool5/new_fs1 pool5/fs1
cannot mount 'pool5/fs1': mountpoint or dataset is busy
property may be set but unable to remount filesystem

root at zns2-n2:/var/adm# zfs set mountpoint=none pool5/fs1
root at zns2-n2:/var/adm# zfs set mountpoint=/pool5/new_fs1_1 pool5/fs1
cannot mount 'pool5/fs1': mountpoint or dataset is busy
property may be set but unable to remount filesystem

>>  I'd quiesce any process that writes there, and make sure it didn't race
to write there while you were mounting pool5/fs1.
I do not see any processes that open files in /pool5/* directories ( I'm
using pfiles utility to check it)
