similar to: zvol of files for Oracle?

How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes). Thanks, -mg This message posted from opensolaris.org

Hello zfs-discuss, Just to be sure - if I create ZFS filesystems on snv_39 and then later I would want just to import that pool on S10U2 - can I safely assume it will just work (I mean nothing new to on-disk format was added or changed in last few snv releases which is not going to be in u2)? I want to put right now (I have to do it now) some data on ZFS and later I want to

Hello zfs-discuss, I wonder if ZFS will be able to take any advantage of Niagara''s built-in crypto? -- Best regards, Robert Milkowski mailto:rmilkowski at task.gda.pl http://milek.blogspot.com

What is a use case of setting a reservation on the base pool object? Say I have a pool of 3 100GB drives dynamic striped (pool size of 300GB), and I set the reservation to 200GB. I don''t see any commands that let me ever reduce a pool''s size, so how is the 200GB reservation used? Related question: is there a plan in the future to allow me to replace the 3 100GB drives with 2

Hello zfs-discuss, Relatively low traffic to the pool but sync takes too long to complete and other operations are also not that fast. Disks are on 3510 array. zil_disable=1. bash-3.00# ptime sync real 1:21.569 user 0.001 sys 0.027 During sync zpool iostat and vmstat look like: f3-1 504G 720G 370 859 995K 10.2M misc 20.6M 52.0G 0 0

If anyone is running this configuration, I have some questions for you about Page83 data errors. This message posted from opensolaris.org

Hello zfs-discuss, If you do ''zpool create -f test A B C spare D E'' and D or E contains UFS filesystem then despite of -f zpool command will complain that there is UFS file system on D. workaround: create a test pool with -f on D and E, destroy it and that create first pool with D and E as hotspares. I''ve tested it on s10u3 + patches - can someone confirm

Is there an existing RFE for, what I''ll wrongly call, "recursively visable snapshots"? That is, .zfs in directories other than the dataset root. Frankly, I don''t need it available in all directories, although it''d be nice, but I do have a need for making it visiable 1 dir down from the dataset root. The problem is that while ZFS and Zones work smoothly

hi all, i''ve been using a SAN LUN as the sole member of a zpool with one additional zfs filesystem. this is a flat SAN fabric, so this LUN was available to other systems on the fabric, and one of them came up with "wrong magic number" for several drives, and, as best i can tell, the vtoc for my zpool LUN was over-written on that host via format labeling to correct the error.

I have a customer who has implemented the following layout: As you can see, he has mostly raidz zvols but has one raidz2 in the same zpool. What are the implications here? Is this a bad thing to do? Please elaborate. Thanks, Scott Gaspard Scott.J.Gaspard at Sun.COM > NAME STATE READ WRITE CKSUM > > chipool1 ONLINE 0 0 0 > >

for s10u2, documentation recommends 3 to 9 devices in raidz. what is the basis for this recommendation? i assume it is performance and not failure resilience, but i am just guessing... [i know, recommendation was intended for people who know their raid cold, so it needed no further explanation] thanks... oz -- ozan s. yigit | oz at somanetworks.com | 416 977 1414 x 1540 I have a hard time

Hello zfs-discuss, I''m writing a script to do automatically snapshots and destroy old one. I think it would be great to add to zfs destroy another option so only snapshots can be destroyed. Something like: zfs destroy -s SNAPSHOT so if something other than snapshot is provided as an argument zfs destroy wouldn''t actually destroy it. That way it would

Hello, is there a way to add a zfs dataset to a zone online? The only info I found is to configure the dataset in the zone via zonecfg then reboot the zone. I would like to be able to add new separated dataset for each new db''s I add in the zone and of course if I need to reboot the zone every time I have to add/remove a db, my users will not be very happy... The only option I found

Hello list, someone (actually neil perrin (CC)) mentioned in this thread: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-December/034340.html that is should be possible to import a pool with failed log devices (with or without data loss ?). >/ />/ Has the following error no consequences? />/ />/ Bug ID 6538021 />/ Synopsis Need a way to force pool startup when

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

Hi zfs-discuss, I have some questions about throttling on ZFS 1) I know that throttling is activating while one sync is waiting for another. (http://blogs.sun.com/roller/page/roch?entry=the_dynamics_of_zfs) Is it possible to throttle only selected processes (e.g. nfsd) ? 2) How can I obtain some statistics about it? I want to know how often throttling is activating on my host etc. 3) Is it

Is there a best practice guide for using zfs as a basic rackable small storage solution? I''m considering zfs with a 2U 12 disk Xeon based server system vs something like a second hand FAS250. Target enviroment is mixature of Xen or VI hosts via iSCSI and nfs/cifs. Being able to take snapshots of running (or maybe paused) xen iscsi vols and re-export then for cloning and remote backup

hi all, I am hoping to move roughly 1TB of maildir format email to ZFS, but I am unsure of what the most appropriate disk configuration on a 3510 would be. based on the desired level of redundancy and usable space, my thought was to create a pool consisting of 2x RAID-Z vdevs (either double parity, or single parity with two hot-spares). using 300GB drives this would give roughly 2.4TB of usable

All, I understand that ZFS gives you more error correction when using two LUNS from a SAN. But, does it provide you with less features than UFS does on one LUN from a SAN (i.e is it less stable). Thanks, Shawn This message posted from opensolaris.org
