zfs discuss - May 2006 - ZFS seems to fall asleep

Hi,

I have Solaris Express snv_27 installed on an x86 pc with 4 SATA drives. I have
1 zpool called data with 16 ZFS filesystems. From times to times, it looks like
ZFS falls asleep, i.e. when I do a df -k, it takes about a second to list each
ZFS filesystem. If I re-issue the command straight away or a couple of minutes
later, it takes a second to list all the filesystems.
I checked in the /var/log and /var/adm directory to see if I could find an error
message, but nothing at all.

Any idea? I know I should probably upgrade to a more recent version of Solaris
Express, but I haven''t figured out how to do that with zones yet.
Thanks a lot in advance.

Hmm, I doubt that ZFS is goiung to sleep, but perhaps the drives are being
spun down, and the time delay is happening while they spin up again?

PS Your name is familiar; did you used to work for Telus in Calgary?
