I tried to run "zfs list" on my system, but looks that this command
will hangs. This command can not return even if I press "contrl+c" as
following:
r...@intel7:/export/bench/io/filebench/results# zfs list
^C^C^C^C
^C^C^C^C
..
When this happens, I am running filebench benchmark with oltp
workl
Thanks, fixes following two issues, I can get the right value:(1) Dividing
offset 0x657800(6649856) by 512 and take it as the iseek value.
(2) Run the dd command on device c2t0d0s0, not c2t0d0.

Find that zio->io_offset is the absolute offset of device, not in sector
unit. And If we need use zdb -R to dump the block, we should use the offset
(zio->io_offset-0x40).

I use following dtrace script to trace the postion of one file on zfs:
#!/usr/sbin/dtrace -qs
zio_done:entry
/((zio_t *)(arg0))->io_vd/
{
zio=(zio_t *)arg0;
printf("Offset:%x and Size:%x\n",zio->io_offset,zio->io_size);
printf("vd:%x\n",(unsigned long)(zio->io_vd));
I have created a pool on external storage with B114. Then I export this pool
and import it on another system with B110.But this import will fail and show
error: cannot import 'tpool': pool is formatted using a newer ZFS version.
Any big change in ZFS with B114 leads to this compatibility issue?
