Re: [zfs-discuss] ZFS problems in dCache
I think I am having the same problem using a different application (Windchill). zfs is consuming hugh amounts of memory and system (T2000) is performing poorly. Occasionally it will take a long time (several hours) to do a snapshot. Normally a snapshot will take a second or two. The application will allow me to break the one directory which has almost 600,000 files in to several directories. I am in the process of doing this now. I never thought it was a good idea to have that many files in one directory.

Re: [zfs-discuss] scrub halts
Gary Gendel wrote: Thanks for the information. I am using the Marvell8sx driver on a vanilla Sunfire v20z server. This project has gone through many frustrating phases... Originally I tried a Si3124 board with the box running a 5-1 Sil Sata multiplexer. The controller didn't understand the multiplexer so I put in a second board and drove the drives directly. However, this didn't work well either and would lock up periodically. I added some published driver patches which made things better, but I would still get periodic kernel panics because of a recursive mutex call. So, I bought the Supermicro 8 channel Sata Marvell card. I tried the multiplexer again, but no luck, so I'm driving each separately again. Occasionally, I would have a system lockup and could only force the system to power down. I believe that this may have been due to a flaky Sata connection internal to the box. Now I'm left with the situation that I described. I've had the same issue on my box. It often (somewhere between every 30 minute to 4th hour) resets the sata ports. It continues fine, but it does halt the machine for some time. Recently after I gave up on debugging and took the machine into production it has started to freeze randomly about once per day. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Solaris 10 8/2007 and Bug tracking...
Folks, I just got an invite to a release event for Sol 10 8/2007. Considering this must mean at some level that the 8/2007 release is going gold in the next week or so, is there anywhere that has a list of includes for bug fixes and RFE related to ZFS that are planned to make it into 8/2007? Also I have noticed an increased amount of bug ID's that are showing no information -- is there some other view in the bug tracking system that is available to see more detail? For example: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6343667 State5-Cause Known (Bug is root caused) (does not tell me anything about the status) Description See comments. (What Comments?) Work Around N/A Thanks!

[zfs-discuss] In guest domains, zones not booting if it is on ZFS file system
Hi, I created guest domains and used sparse root model zones on a ZFS file system. Zone configuration and installation went on successfully, but it does not boot. No messages on the console. So, i installed it on a UFS file system, then local zones were running. Is there any limitation to run local zone on ZFS file system, inside a guest domain?

Re: [zfs-discuss] zfs iscsi storage for virtual machines
I have hundreds of Xen-based virtual machines running off a ZFS/iSCSI service; yes, it's viable. I can't speak for CentOS specifically; our infrastructure is using Debian Etch with our own build of Xen. How does ZFS handle snapshots of large files like VM images? Is replication done on the bit/block level or by file? In otherwords, does a snapshot of a changed VM image take up the same amount of space as the image or only the amount of space of the bits that have changed within the image? I'm also strongly considering going with NFS or AFS instead of iSCSI so I don't have to deal with management of an extra filesystem layer. The VMWare community is split on which is faster. Are there any significant benefits to either one on the ZFS side? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

ZFS uses Copy On Write to implement snap shots. No replication is done. When changes are made only the blocks changed are different (the originals are kept by the snapshot).

[zfs-discuss] is send/receive incremental
I'd like to send a backup of my filesystem offsite nightly using zfs send/receive. Are those done incrementally so only changes move or would a full copy get shuttled across everytime? -- Pete ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] is send/receive incremental
You can do it either way. Eric Kustarz has a good explanation of how to set up incremental send/receive on your laptop. The description is on his blog: http://blogs.sun.com/erickustarz/date/20070612 The technique he uses is applicable to any ZFS filesystem. -j On Wed, Aug 08, 2007 at 04:44:16PM -0600, Peter Baumgartner wrote: I'd like to send a backup of my filesystem offsite nightly using zfs send/receive.
