Hello,
I have an X4540 running 2008.11 snv_106
I rebooted it tonight since I had a hung iSCSI connection to the Sun
box that wouldn't go away (couldn't delete that particular ZFS
filesystem till the initiator drops connection)
Upon reboot, the system will hang after printing the license header. I
Hi all,
Recently there's been discussion [1] in the Linux community about how
filesystems should deal with rename(2), particularly in the case of a crash.
ext4 was found to truncate files after a crash, that had been written with
open("foo.tmp"), write(), close() and then rename("foo.tmp", "foo").
Wow Craig - thank you so much for that thorough response.
I am only using 1 vdev and I didn't realize two things:
1) that 50 GB on each of the 300s is essentially wasted. I thought it
would spread 300 GB of parity across all 6 disks, leaving me with 1350
GB of "data" space. Instead, you're saying

no, this is an incorrect diagnosis. The problem is that by
using the -V option, you created a volume, not a file system.
That is, you created a raw device. You could then newfs
a ufs file system within the volume, but that is almost certainly
not what you want.

Ok, Cindy. Thanks. I would like to have one big pool and divide it into
separate file systems for an Oracle database. What I had before was a separate
pool for each file system. So does it look I have to go back to what I had
before?

Grant,
If I'm following correctly, you can't mount a ZFS resource
outside of the pool from which the resource resides.
Is this a UFS directory, here:
# mkdir -p /opt/mis/oracle/data/db1
What are you trying to do?
