Re: [zfs-discuss] Zpool import not working - I broke my pool...
Any updates on this ? I created a pool in 5/08, then added a slog device which sadly failed. I can no longer mount the pool, it gives a "cannot import 'mypool': one or more devices is currently unavailable". I have tried it with the latest OpenSolaris pre-release (2008.11, based on Nevada build 99) and still no luck. Please advise, James -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Pool corruption avoidance
Hi, Unfortunately, every now and then someone has his zpool corrupt, with no tools to fix it! This is due to either zfs bugs, or hardware lying about whether the bits really hit the platters. I am evaluating what I should be using for storing VMware ESX VM images (ext3 or zfs on NFS). I really really want zfs snapshots, but loosing the pool is going to be a royal pain for small businesses. My questions are: 1- What are the best practices to avoid pool corruption (even if it incurs a performance hit) ? 2- I remember a suggested idea that zfs would iterate back in time when mounting a zpool till it finds a fully written pool and uses that, thus avoiding corruption. Is there an RFE for that yet ? I'd like to subscribe to that, and I might even delay jumping on the zfs wagon till it's got this recovery feature!

Re: [zfs-discuss] HELP! SNV_97, 98, 99 zfs with iscsitadm and VMWare!
Ciao, Your GUID's must not be the same an NAA is already established on the targets and if you previously tried to initialize the LUN with VMware it would have assigned the value in the VMFS header wich is now stored on your raw ZFS backing store. This will confuse VMware and it will remember it now some where in its definitions. You need to remove the second datastore from VMware and delete the target definition and ZFS backing store. Once you recreate the backing and target you should have a new GUID and iqn which should cure the issue.

Re: [zfs-discuss] HELP! SNV_97, 98, 99 zfs with iscsitadm and VMWare!
According to the svccfg(1M) man page: http://docs.sun.com/app/docs/doc/819-2240/svccfg-1m?a=view ...it should be just 'export' without a leading '-' or '--'. I've been googling on NAA and this is the 'Network Address Authority', It seems to be yet another way of uniquely identifying a target & Lun, and is apparently to be compatble with the way that Fibre Channel & SAS do this. For futher details, see: http://tools.ietf.org/html/rfc3980 "T11 Network Address Authority (NAA) Naming Format for iSCSI Node Names" I also found this blog post: http://timjacobs.blogspot.com/2008/08/matching-luns-between-esx-hosts-and-vcb.html ...which talks about Vmware ESX and NAA. For anyone interested in the code fix's to the solaris iscsi target to support Vmware ESX server, take a look at these links: http://hg.genunix.org/onnv-gate.hg/rev/29862a7558ef http://hg.genunix.org/onnv-gate.hg/rev/5b422642546a Tano, based on the above, I would say you need unique GUID's for two separate Targets/LUNS.

[zfs-discuss] Best practice recommendations for backing up to ZFS Fileserver
Greetings. I am currently looking into setting up a better backup solution for our family. I own a ZFS Fileserver with a 5x500GB raidz. I want to back up data (not the OS itself) from multiple PCs running linux oder windowsXP. The linux boxes are connected via 1000Mbit, the windows machines either via gigabit as well or 54Mbit WPA encrypted WLAN. So far i've set up sharing via NFS on the Solaris box and it works well from both Linux and Windows (via SFU). I am looking for a solution to do incremental backups without wasting space on the fileserver and I want to be able to access a single file in the backup in differnt versions without much hassle. I think it can be done easily with ZFS and Snapshots? What would be good ways to get the files to the fileserver? For linux I thought of using rsync to sync the files over, than do a snapshot to preserve that backup state. Would you recommend using rsync with NFS or over ssh? (I assume the network is save enough for our needs.) Are there better alternatives? How to best get the data from the Windows machines to the Solaris box? Just copying them over by hand would not delete files on the fileserver in case some files are deleted on the windows box in between different backups. Using rsync on windows is only possible with cygwin emulation. Maybe there are better methods? Anyone have a similar setup, recommendations, or maybe something I could use as an idea?

May it be that your network has different performance levels for different transport types? For our network we have disabled pause frames completey and rely only on TCP internal mechanisms to prevent flooding/blocking.
