The question: is there an issue running: ZFS and QFS on the same file server?
The details:
We have a 2540 raid controller with 4 raidsets. Each raidset presents 2 slices
to the OS. one slice (slice 0) from each raidset is a separate qfs filesystems
shared among 7 servers running qfs 4.6patch6.
One of the above servers has created on zfs pool using the other 4 slices
(slice 1 from each of the 4 raidsets)
pool: zfs_hpf
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
zfs_hpf ONLINE 0 0 0

zpool upgrade
This system is currently running ZFS pool version 15.
zfs upgrade
This system is currently running ZFS filesystem version 4.
What we have been seeing is that the emulex HBAs attaching to the 2540 through
a sanswitch have been dying periodically, particularly under load.
luxadm -e port
/devices/p...@1,0/pci1022,7...@2/pci10df,f...@1/f...@0,0:devctl NOT
CONNECTED
/devices/p...@1,0/pci1022,7...@2/pci10df,f...@1,1/f...@0,0:devctl NOT
CONNECTED
We need to reboot to get the hba to reconnect.
we have never seen this on the other fileservers and are wondering if the HBA
is faulty or is there an issue running:
ZFS and QFS on the same file server?
Has anyone seen this?
As an FYI we are running
cat /etc/release
Solaris 10 10/09 s10x_u8wos_08a X86
