Hello list,
I'm having trouble with a server holding a lot of data. After a few
months of uptime, it is currently rebooting from a lockup (reason
unknown so far) but it is taking hours to boot up again. The boot
process is stuck at the stage where it says:

Hi Frank,
you might face the problem of lots of snapshots of your filesystems.
For each snapshot a device is created during import of the pool. This can
easily lead to an extend startup time.
At my system it took about 15 minutes for 3500 snapshots.

I am totally aware of these differences, but it seems some people
think RAIDz is nonsense unless you don't need speed at all. My
testing shows (so far) that the speed is quite good, far better than
single drives. Also, as Eric said, those speeds are for random i/o.
I doubt there is very

The spec sheets claim 512b sectors, so hopefully it'll work.

Hi,
I wonder what is the better option to install the system on solaris ufs
and zfs sensitive data on whether this is the best all on zfs?
What are the pros and cons of such a solution?

Dedup? Taking a long time to boot after hard reboot after lookup?
I'll bet that it hard locked whilst deleting some files or a dataset that
was dedup'd. After the delete is started, it spends *ages* cleaning up the
DDT (the table containing a list of dedup'd blocks). If you hard lock in the

UFS is already unavailable as a boot option. It's only

In order to test random reads, you have to configure iozone to use a data set
which is much larger than physical ram. Since iozone will write a big file
and
then immediately afterward, start reading it
The only situation I can think of where UFS would be advantageous over
ZFS might be in a low memory situation. ZFS loves memory.
But to answer the original question, ZFS is where you want to be.
