NFS/ZFS performance problems - txg_wait_open() deadlocks?
...quot;txg_wait_open+"
360
bash-3.00# cat nfsd.txt | grep "txg_wait_open+" | grep -c "337d1e"
360
So all those txg_wait_open are for the same transaction group - txg_wait_open+0x58(6000ad0c910, 337d1e,
All the other threads were in:
bash-3.00# cat nfsd.txt | grep -c "zfs_range_lock_reader+"
289
Several different dnodes (however several threads to the same dnode).
Also using ''zpool iostat 1'' while nfsd was shuting down I could see mostly reads and some writes every 40-60s.
Why nfsd was closing for almost 3 minutes? Because we were sitting i...

unaccounted for daily growth in ZFS disk space usage
We finally flipped the switch on one of our ZFS-based servers, with
approximately 1TB of 2.8TB (3 stripes of 950MB or so, each of which is
a RAID5 volume on the adaptec card). We have snapshots every 4 hours
for the first few days. If you add up the snapshot references it
appears somewhat high versus daily use (mostly mail boxes, spam, etc

Get your SXCE on ZFS here!
With the release of the Nevada build 90 binaries, it is now possible to install SXCE directly onto a ZFS root filesystem, and also put ZFS swap onto a ZFS filesystem without worrying about having it deadlock. ZFS now also supports crash dumps!
To install SXCE to a ZFS root, simply use the text-based installer, after choosing "Solaris Express" from the boot menu on the DVD.

The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see...

virsh troubling zfs!?
Hi and hello,
I have a problem confusing me. I hope someone can help me with it.
I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines.
Commands (for completion):
[i]zfs create rpool/vms[/i]
[i]zfs create rpool/vms/vm1[/i]
[i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i]
This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the according [i]/dev/zvol/dsk/rpool/vms/vm1/vm1-dsk[/i...

copy complete zpool via zfs send/recv
Hi,
I want to move all the ZFS fs from one pool to another, but I don''t want
to "gain" an extra level in the folder structure on the target pool.
On the source zpool I used zfs snapshot -r tank at moveTank on the root fs
and I got a new snapshot in all sub fs, as expected.
Now, I want to use zfs send -R tan...
