Hi All, I have corefile where we see NULL pointer de-reference PANIC as we have sent (deliberately) NULL pointer for return value. vdev_disk_io_start() ... ... error = ldi_ioctl(dvd->vd_lh, zio->io_cmd, (uintptr_t)&zio->io_dk_callback, FKIOCTL, kcred, NULL); ldi_ioctl() expects last parameter as an integer pointer ( int *rvalp). I see that in strdoictl(). Corefile I am analysing has similar BAD trap while trying to...

Hi all, You will find in attachment to this mail some benchmarks we made on Linux with pios over ZFS-DMU. There are some interesting things about ZFS tuning and some ideas for breaking a bottleneck we identified in DMU.

After an upgrade of a busy server to Oracle Solaris 10 9/10, I notice a process called zpool-poolname that has 99 threads. This seems to be a limit, as it never goes above that. It is lower on workstations. The `zpool'' man page says only: Processes Each imported pool has an associated process, named zpool- poolname. The threads in this process are the pool''s

I'm trying to destroy a zfs array which I recently created. It contains nothing of value. # zpool status pool: storage state: ONLINE status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using 'zpool replace'.

I contacted the author of ''lsof'' regarding the missing ZFS support. The command works but fails to display any files that are opened by the process in a ZFS filesystem. He indicates that the required ZFS kernel structure definitions (header files) are not shipped with the OS. He further indicated that he rummaged through the OpenSolaris source tree and the files doesn''t
