Re: [zfs-discuss] Terrible ZFS performance on a Dell 1850 w/ PERC 4e/Si (Sol10U6)
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... - Robert Loper -- Forwarded message -- From: Andrei Ghimus ghi...@gmail.com To: zfs-discuss@opensolaris.org Date: Mon, 30 Aug 2010 11:05:27 PDT Subject: Re: [zfs-discuss] Terrible ZFS performance on a Dell 1850 w/ PERC 4e/Si (Sol10U6) 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 mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] ZFS Send/Receive Question
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? -- Robert Loper rlo...@gmail.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] SUMMARY: Any way to fix ZFS sparse file bug #6792701
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. -- Robert Loper ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Can you clarify what this IDR is? I do not have Sun Support on this specific server. - Robert Loper On Wed, Mar 3, 2010 at 11:51 AM, Francois Napoleoni francois.napole...@sun.com wrote: From my experience with customer hitting this bug, installing the now obsolete IDR and rebooting was enoug hto get ride of these sparse file bug.

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.

Re: [zfs-discuss] Any way to fix ZFS sparse file bug #6792701
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? - Robert On Wed, Mar 3, 2010 at 12:08 PM, Geoff Shipman geoff.ship...@sun.comwrote: IDR's are fixes for troubles from the initial development state.
