Hi, I do have a disk array that is providing striped LUNs to my Solaris box. Hence I''d like to simply concat those LUNs without adding another layer of striping. Is this possibile with ZFS? As far as I understood, if I use zpool create myPool lun-1 lun-2 ... lun-n I will get a RAID0 striping where each data block is split across all "n" LUNs. If that''s

Hello all, First off, i''m talking about a SXDE build 89. Sorry if that was discussed here before, but i did not find anything related on the archives, and i think is a "weird" issue... If i try to remove a specific file, i got: # rm file1 rm: file1: No such file or directory # rm -rf dir2 rm: Unable to remove directory dir2: Directory not empty Take a look: ------- cut

if you have N processes reading the same file sequentially (where file size is much greater than physical memory) from the same starting position, should I expect that all N processes finish in the same time as if it were a single process? In other words, if you have one process that reads blocks from a file, is it "free" (meaning no additional total I/O cost) to have another process

Adam, With the blog entry[1] you''ve made about gzip for ZFS, it raises a couple of questions... 1) It would appear that a ZFS filesystem can support files of varying compression algorithm. If a file is compressed using method A but method B is now active, if I truncate the file and rewrite it, is A or B used? 2) The question of whether or not to use bzip2 was raised in the

Hello all... I''m migrating a nfs server from linux to solaris, and all clients(linux) are using read/write block sizes of 8192. That was the better performance that i got, and it''s working pretty well (nfsv3). I want to use all the zfs'' advantages, and i know i can have a performance loss, so i want to know if there is a "recomendation" for bs on nfs/zfs, or

Would it be worthwhile to implement heuristics to auto-tune ''recordsize'', or would that not be worth the effort? -- Regards, Jeremy

Hello all, I was thinking if such scenario could be possible: 1 - Export/import a ZFS filesystem in two solaris servers. 2 - Export that filesystem (NFS). 3 - Mount that filesystem on clients in two different mount points (just to authenticate in both servers/UDP). 4a - Use some kind of "man-in-the middle" to auto-balance the connections (the same IP on servers) or 4b - Use different

Hi, my system (solaris b77) was physically destroyed and i loosed data saved in a zpool mirror. The only thing left is a dettached vdev from the pool. I''m aware that uberblock is gone and that i can''t import the pool. But i still hope their is a way or a tool (like tct http://www.porcupine.org/forensics/) i can go too recover at least partially some data) thanks in advance for

Hi, In migrating from **VM to ZFS am I going to have an issue with Major/Minor numbers with NFS mounts? Take the following scenario. 1. NFS clients are connected to an active NFS server that has SAN shared storage between the active and standby nodes in a cluster. 2. The NFS clients are using the major/minor numbers on the active node in the cluster to communicate to the NFS active server. 3.

Hello folks, I have a question and a small problem... I did try to replicate my zfs with all the snaps, so I did run few commands: time zfs send mypool/d at 2006_month_10 | zfs receive mypool2/d at 2006_month_10 real 6h35m12.34s user 0m0.00s sys 29m32.28s zfs send -i mypool/d at 2006_month_10 mypool/d at 2006_month_12 | zfs receive mypool/d at 2006_month_12 real 4h49m27.54s user

Zpool split is a wonderful feature and it seems to work well, and the choice of which disk got which name was perfect! But there seems to be an odd anomaly (at least with b132) . Started with c0t1d0s0 running b132 (root pool is called rpool) Attached c0t0d0s0 and waited for it to resilver Rebooted from c0t0d0s0 zpool split rpool spool Rebooted from c0t0d0s0, both rpool and spool were mounted

In another thread recursive snapshot creation was found atomic so that it is done quickly, and more important, all at once or nothing at all. Do you know if recursive destroying and renaming of snapshots are atomic too? Regards Henrik Heino

I just had a quick play with gzip compression on a filesystem and the result was the machine grinding to a halt while copying some large (.wav) files to it from another filesystem in the same pool. The system became very unresponsive, taking several seconds to echo keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty of grunt for this. Comments? Ian

Here is a proposal for a new ''copies'' property which would allow different levels of replication for different filesystems. Your comments are appreciated! --matt A. INTRODUCTION ZFS stores multiple copies of all metadata. This is accomplished by storing up to three DVAs (Disk Virtual Addresses) in each block pointer. This feature is known as "Ditto Blocks".

Hi All, ZPOOL / ZFS commands writes EFI label on a device if we create ZPOOL/ZFS fs on it. Is it true ? I formatted a device with VTOC lable and I created a ZFS file system on it. Now which label the ZFS device has ? is it old VTOC or EFI ? After creating the ZFS file system on a VTOC labeled disk, I am seeing the following warning messages. Feb 3 07:47:00 scoobyb

Hi Is it possible to convert live 3 disks zpool from raidz to raidz2 And is it possible to add 1 new disk to raidz configuration without backups and recreating zpool from cratch. Thanks This message posted from opensolaris.org
