Re: [zfs-discuss] Terrible ZFS performance on a Dell 1850 w/ PERC 4e/Si (Sol10U6)

2010-08-31 Thread Robert Loper
I ran into this issue on my Dell 1850s also.  You'll need to go into BIOS,
change the PERC controller mode from RAID to SCSI and reboot.  Then when the
system comes back up it will give a warning about switching RAID controller
modes and data loss (Have Backups)!.  Then if you boot from DVD/Jumpstart
you should see 2 disks and just do a ZFS 2 disk mirror for rpool.

Hope this helps...

I have the same problem you do, ZFS performance under Solaris 10 u8 is
horrible.

When you say passthrough mode, do you mean non-RAID configuration?
And if so, could you tell me how you configured it?

The best I can manage is to configure each physical drive as a RAID 0 array
then export that as a logical drive.

All tips/suggestions are appreciated.

[zfs-discuss] ZFS Send/Receive Question

2010-04-12 Thread Robert Loper
I am trying to duplicate a filesystem from one zpool to another zpool.  I
don't care so much about snapshots on the destination side...I am more
trying to duplicate how RSYNC would copy a filesystem, and then only copy
incrementals from the source side to the destination side in subsequent runs
until I can complete a switch-over.  What would be some examples of the
syntax in zfs send/receive?

[zfs-discuss] SUMMARY: Any way to fix ZFS sparse file bug #6792701

2010-03-05 Thread Robert Loper
Original question:

I have a Solaris x86 server running update 6 (Solaris 10 10/08
s10x_u6wos_07b X86).  I recently hit this sparse file bug when I deleted a
512GB sparse file from a 1.2TB filesystem and the space was never freed up.
What I am asking is would there be any way to recover the space in the
filesystem without having to destroy and recreate it?  I am assuming before
trying anything I would need to update the server to U8.


Answer:

Installing kernel patch 141444-09 (SPARC) or 141445-09 (x86) (included in a
Live-update to Solaris 10 update 8) on my system showed the filesystem will
600GB more free space.  I did not need to export/import or upgrade the
pool...it was just available.

Thanks to all who responded to this.

Can you clarify what this IDR is?  I do not have Sun Support on this
specific server.

 This avoids future problems with the CR but if your currently effected
 by the problem the fix doesn't clear the troubles.

 I believe a backup of the data, then destroy of the file system, then
 recreating it and restoring is method to clear the space.  With the
 later kernel the problem is avoided in the future.

So the question remains... if I install patch 14144{45}-09 (by a LU to
Solaris 10 upd 8) will that allow the filesystem (not an rpool) to free up
the space?
