Re: [zfs-discuss] pool use from network poor performance
Hi Instaled pci addon network card and disabled nvidia onboarad network. All started to work as should. So nge and nv_sata drivers does not work in b134 when shared IRQ is used. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] pool use from network poor performance
Hi Here is more specs. MB: K8N4-E SE - AMD Socket 754 CPU - NVIDIA® nForce™ 4 4X - PCI Express Architecture - Gigabit LAN - 4 SATA RAID Ports - 10 USB2.0 Ports http://www.asus.com/product.aspx?P_ID=TBx7PakpparxrK89templete=2 Now situation is this : with ftp : i can upload to datapool with speed ~45MB/s download from datapool only with speed ~ 750 KB/s So it is now read performance that is a problem. Could it really be that nvidia network and sata drivers now share same IRQ and that's why performance is slow. Mar 23 19:35:01 hostname unix: [ID 954099 kern.info] NOTICE: IRQ20 is being shared by drivers with different interrupt levels. This is just odd as this issue come when only changed pool physical disks and also changed raidz to raidz2 and also update to build 134 -- 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 use from network poor performance
Hi i have now two pools rpool 2-way mirror ( pata ) data 4-way raidz2 ( sata ) if i access to datapool from network , smb , nfs , ftp , sftp , jne... i get only max 200 KB/s speeds compared to rpool that give XX MB/S speeds to and from network it is slow. Any ideas what reasons might be and how try to find reason. Locally datapool works reasonable fast for me. # date mkfile 1G testfile date Tuesday, March 23, 2010 07:52:19 AM EET Tuesday, March 23, 2010 07:52:36 AM EET Some information about system. # cat /etc/release OpenSolaris Development snv_134 X86 Copyright 2010 Sun Microsystems, Inc.

[zfs-discuss] Q : recommendations for zpool configuration
Greetings I would like to get your recommendation how setup new pool. I have 4 new 1.5TB disks reserved to new zpool. I planned to crow/replace existing small 4 disks ( raidz ) setup with new bigger one. As new pool will be bigger and will have more personally important data to be stored long time, i like to ask your recommendations should i create recreate pool or just replace existing devices. I have noted there is now raidz2 and been thinking witch woul be better. A pool with 2 mirrors or one pool with 4 disks raidz2 So at least could some explain these new raidz configurations Thanks -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Q : recommendations for zpool configuration
Thanks for comments So possible choises are : 1) 2 2-way mirros 2) 4 disks raidz2 BTW , can raidz have spare ? so is there one posible choise more : 3 disks raidz with 1 spare ? Here i prefer data availibility not performance. And if need sometime to expand / change setup it is then that time problem -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Odd zpool / zfs issue
Hi I have one usb hard drive that shows in zpool import as zpool that does not exist in disk anymore # zpool import pool: usb1 id: 8159001826765429865 state: FAULTED status: The pool metadata is corrupted. action: The pool cannot be imported due to damaged devices or data. The pool may be active on another system, but can be imported using the '-f' flag. see: http://www.sun.com/msg/ZFS-8000-72 config: usb1FAULTED corrupted data c5t0d0p0 ONLINE I tried some time ago to make mirrored usb zpool but it failed And been using this disk now in windows and it is new formatted as ntfs But every time i boot snv it complains about this disk ...

[zfs-discuss] Q : relayout disks
Hi I have planned to relayout current mirrored boot disk configuration which comes from days no zfs boot. History - I just converted old ufs boot slices to zfs boot , those where mirrored using solaris volume manager to zfs boot... Current layout is : 2 disks as c0d0 and c1d0 NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 mirror ONLINE 0 0 0 c0d0s0 ONLINE 0 0 0 c1d0s0 ONLINE 0 0 0 NAME STATE READ WRITE CKSUM localpool ONLINE 0 0 0 mirror ONLINE 0 0 0 c0d0s5 ONLINE 0 0 0 c1d0s5 ONLINE 0 0 0 localpool is now emptied so no matter even delete it , but how resize rpool to be fully over disks c0d0 and c1d0 as mirror. I know replace mirror device one-by-one will do the job in zpool level but how about zfs boot?? is reinstall only way ??? Or can it handle this as live change So like to get new setup : NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 mirror ONLINE 0 0 0 c0d0 ONLINE 0 0 0 c1d0 ONLINE 0 0 0 Thanks This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Q : change disks to get bigger pool
Hi I have raidz pool raidz1 ONLINE 0 0 0 c2d0ONLINE 0 0 0 c3d0ONLINE 0 0 0 c4d0ONLINE 0 0 0 c5d0ONLINE 0 0 0 That is now getting full. Plan is to replace disks with new and larger disks. So will pool get bigger just by replasing all 4 disks one-by-one ? And if it will get larger how this should be done , fail disks one-by-one .. or ??? Or is data backup and pool recreation only way to get bigger pool Thanks This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] DBMS on zpool
Hi Just playing around with zfs , trying to locate DBMS data files to zpool. DBMS i mean here are oracle and informix. currently noticed that read operations perfomance is excelent but all write operations are not and also write operations performance variates a lot. My quess for not so good write performance and write performance variation is double buffering , DBMS buffers and zfs caching. together. Have anyone seen or tested best practices how should DBMS setup be implemented using zpool ; zfs or zvol.

[zfs-discuss] Tunable parameter to zfs memory use
Hi been using now zfs since 06/06 u2 release has been out. one thing have notised. zfs eats a lot of memory. right after boot mem usage is about 280M but after accessing zfs disks usage rises fast to be 900M. and it seems to stay in level of 90% of tot mem. also noted it frees used mem but running heavy apps you see performace impact while zfs frees memory to other use. now idea: could there be /etc/system tunable parameter for zfs so we could manually set % of total memory zfs can use. like : zfs_max_phys_mem 30% would tell zfs that it can use 30% of available memory. and via versa zfs_min_phys_mem 10% would tell zfs that it can allways use 10% of available memory. -- these maybe need to global values for all zfs filesystems or just simple zfs option that can be set as other zfs options , like compression, etc... then this setting could be easily per zfs filesystem Thanks This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
