Going back to your USB remove test, if you protect that disk
at the ZFS level, such as a mirror, then when the disk is removed
then it will be detected as removed and zfs status will show its
state as removed and the pool as degraded but it will continue
to function, as expected.

Hey Brent,
On the Sun hardware like the Thumper you do get a nice bright blue ready to
remove led as soon as you issue the cfgadm -c unconfigure xxx command. On
other hardware it takes a little more care, I'm labelling our drive bays up
*very* carefully to ensure we always remove the right
I'd expect that to work personally, although I'd just drop one of your boot
mirrors in myself. That leaves the second drive untouched for your other
server. It also means that if it works you could just wipe the old snv_70b and
re-establish the boot mirrors on each server with them.
This

No. You need a user who can take on the role.

want to disable write cache on the disk drives in our J4200 JBODs so
that fsync() actually writes to disk, not just to the cache on the
drive.
I did
this using 'format -e', but it displays a warning about the drive being
part of a zpool and also it says that the change is not permanent.
I have done a bit of testing, and so far so good really.
I have a Dell 1800 with a Perc4e and a 14 drive Dell Powervault 220S.
I have a RaidZ2 volume named 'tank' that spans 6 drives. I have made 1 drive
available as a spare to ZFS.
Normal array:
# zpool status
pool: tank
state: ONLINE
I'm used to using fstat() and other calls to get
atime, ctime, and mtime values, but I understand that the znode also
stores a files creation time in crtime attribute.
Which system call can I use to retrieve this information?
