similar to: NFS and ZFS, a fine combination

Hi all, I have a home server based on SNV_127 with 8 disks; 2 x 500GB mirrored root pool 6 x 1TB raidz2 data pool This server performs a few functions; NFS : for several ''lab'' ESX virtual machines NFS : mythtv storage (videos, music, recordings etc) Samba : for home directories for all networked PCs I backup the important data to external USB hdd each day. I previously had

Is it true that Solaris 10 u4 does not have any of the nice ZIL controls that exist in the various recent Open Solaris flavors? I would like to move my ZIL to solid state storage, but I fear I can''t do it until I have another update. Heck, I would be happy to just be able to turn the ZIL off to see how my NFS on ZFS performance is effected before spending the $''s. Anyone

I''m working with a Cyrus IMAP server running on a T2000 box under Solaris 10 10/09 with current patches. Mailboxes reside on six ZFS filesystems, each containing about 200 gigabytes of data. These are part of a single zpool built on four Iscsi devices from our Netapp filer. One of these ZFS filesystems contains a number of global and per-user databases in addition to one sixth of the

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

This question is concerning ZFS. We have a Sun Fire V890 attached to a EMC disk array. Here''s are plan to incorporate ZFS: On our EMC storage array we will create 3 LUNS. Now how would ZFS be used for the best performance? What I''m trying to ask is if you have 3 LUNS and you want to create a ZFS storage pool, would it be better to have a storage pool per LUN or combine the 3

Dear all, this is my first message to this mailing list - please advise if it is not the right place for the subject I've been using R very intensively the last 3-4 years and one of the most tedious tasks is modification of lookup or conversion tables So far, I have not found functions that create the commands for creating objects (vectors, data frames) based on the objects themselves -

I have historically noticed that in ZFS, when ever there is a heavy writer to a pool via NFS, the reads can held back (basically paused). An example is a RAID10 pool of 6 disks, whereby a directory of files including some large 100+MB in size being written can cause other clients over NFS to pause for seconds (5-30 or so). This on B70 bits. I''ve gotten used to this behavior over NFS, but

Hi all, I''ve got a solaris 10 running 9/10 on a T3. It''s an oracle box with 128GB memory RIght now oracle . I''ve been trying to load test the box with bonnie++. I can seem to get 80 to 90 K writes, but can''t seem to get more than a couple K for writes. Any suggestions? Or should I take this to a bonnie++ mailing list? Any help is appreciated. I''m kinda

Hi. I''m all set for doing performance comparsion between Solaris/ZFS and FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I think I''m ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the links to disks are the bottleneck, so I''m going to use not more than 4 disks, probably.

Hi all, At OLS last month I presented about doing automated client/server testing of NFSv4. In and after that talk there was some discussion with Steve French about using the same framework for testing Samba, so I thought it might be worthwhile to post about the framework on this list. We've also just put out a new 1.6 release of Crucible; I've attached the release notice below. The

Hi, for zfs raidz1, I know for random io, iops of a raidz1 vdev eqaul to one physical disk iops, since raidz1 is like raid5 , so is raid5 has same performance like raidz1? ie. random iops equal to one physical disk''s ipos. Regards Victor -- This message posted from opensolaris.org

Hi, I deployed ZFS on our mailserver recently, hoping for eternal peace after running on UFS and moving files witch each TB added.

I need some clarification on the FOID handed to zil_commit. I wrote a dscript to watch entry and return of zil_commit_writer. Here is an example output: <pre> 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211310 : FOID 129644 Completed in 0 ms 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211324 : FOID 129644 Completed in 0 ms 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211386

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

Hi, as I have learned from the discussion about which SSD to use as ZIL drives, I stumbled across this article, that discusses short stroking for increasing IOPs on SAS and SATA drives: http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html Now, I am wondering if using a mirror of such 15k SAS drives would be a good-enough fit for a ZIL on a zpool that is mainly used for file

I recently got a new SSD (ocz vertex LE 50gb) It seems to work really well as a ZIL performance wise. My question is, how safe is it? I know it doesn''t have a supercap so lets'' say dataloss occurs....is it just dataloss or is it pool loss? also, does the fact that i have a UPS matter? the numbers i''m seeing are really nice....these are some nfs tar times before

We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)
