similar to: 2-way mirror or RAIDZ?

On a system still running nv_30, I''ve a small RaidZ filled to the brim: 2 3 root at mir pts/9 ~ 78# uname -a SunOS mir 5.11 snv_30 sun4u sparc SUNW,UltraAX-MP 0 3 root at mir pts/9 ~ 50# zfs list NAME USED AVAIL REFER MOUNTPOINT mirpool1 33.6G 0 137K /mirpool1 mirpool1/home 12.3G 0 12.3G /export/home mirpool1/install 12.9G

I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact. I want zfs to get access to the full disk instead of a slice. I believe like c8d0 instead off c8d0s1. I wanted to do this 1 disk at a time and let it resilver. what is the proper way to do this. I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1 but it didn''t let me do that. then I

Hi, We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe. Each disk (of 4) is divided up like this / 6GB UFS s0 Swap 8GB s1 /var 6GB UFS s3 Metadb 50MB UFS s4 /data 48GB ZFS s5 For SVM we do a 4 way mirror on /,swap, and /var So we have 3 SVM mirrors d0=root (sub mirrors d10, d20, d30, d40) d1=swap (sub mirrors d11, d21,d31,d41)

Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Hi, one quick&dirty way of backing up a pool that is a mirror of two devices is to zpool attach a third one, wait for the resilvering to finish, then zpool detach it again. The third device then can be used as a poor man''s simple backup. Has anybody tried it yet with a striped mirror? What if the pool is composed out of two mirrors? Can I attach devices to both mirrors, let them

Hi, I have a small Linux server PC at home (Intel Core2 Q9300, 4 GB RAM), and I''m seriously considering switching to OpenSolaris (Indiana, 2008.11) in the near future, mainly because of ZFS. The idea is to run the existing CentOS 4.7 system inside a VM and let it NFS mount home directories and other filesystems from OpenSolaris. I might migrate more services from Linux over time, but for

Hello, I''m quite interested in ZFS, like everybody else I suppose, and am about to install FBSD with ZFS. On that note, i have a different first question to start with. I personally am a Linux fanboy, and would love to see/use ZFS on linux. I assume that I can use those ZFS disks later with any os that can work/recognizes ZFS correct? e.g. I can install/setup ZFS in FBSD, and later use

Hi all, I currently have four drives in my OpenSolaris box. The drives are split into two mirrors, one mirror containing my rpool (disks 1 & 2) and one containing other data (disks 2 & 3). I''m running out of space on my data mirror and am thinking of upgrading it to two 2TB disks. I then considered replacing disk 2 with a 2TB disk and making a RAIDz from the three new drives.

Hi, I installed a zpool containing of zpool __mirror ____disk1 500gb ____disk2 500gb __raidz ____disk3 1tb ____disk4 1tb ____disk5 1tb It works fine, but it displays the wrong size (terminal -> zpool list). It should be 500gb (mirrored) + 2TB (3TB raidz) = 2,5 TB, right? But it displays it has 3,17TB diskspace available. I first created the mirror and then added the raidz to it (zpool add

OK, I''ve been putting off this question for a while now, but it eating at me, so I can''t hold off any more. I have a nice 8 gig memory stick I''ve formated with the ZFS file system. Works great on all my Solaris PC''s, but refuses to work on my Sparc processor. So I''ve formated it on my Sparc machine (Blade 2500), works great there now, but not on

Hi, I want to disable extended attributes in my zfs on s10u4. I found out that the command to do is zfs set xattr=off <poolname>. But, I do not see this option in s10u4. How can I disable zfs extended attributes on s10u4? I''m not in the zfs-discuss alias. Please respond to me directly. Thanks Balaji

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

Hey folks, Does anybody know if any of these are on the roadmap for ZFS, or have any idea how long it''s likely to be before we see them (we''re in no rush - late 2008 would be fine with us, but it would be nice to know they''re being worked on)? I''ve seen many people ask for the ability to expand a raid-z pool by adding devices. I''m wondering if it

Hi All, I had a slice with zfs file system which I want to mirror, I followed the procedure mentioned in the amin guide I am getting this error. Can you tell me what I did wrong? root # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT export 254G 230K 254G 0% ONLINE - root # echo |format Searching for disks...done

Greetings all- I have a new X4200 that I''m getting ready to deploy. It has four 146 GB SAS drives. I''d like to setup the box for maximum redundancy on the data stored on these drives. Unfortunately, it looks like ZFS boot/root aren''t really options at this time. The LSI Logic controller in this box only supports either a RAID0 array with all four disks, or a RAID 1

Hi. I want use xen with dynamic slices. For example, I have 20 domU based on FreeBSD, xen hypervisor 3.3.1, Debian Lenny dom0 system. All domUs have 80Gb LVM partitions, but realy they use 20 of this 80Gb and I want to create more domU''s. How can I do it? I know that some virtualisation have possibility to do dynamic slices(4 example Virtul box) -- Best Regards, alex.faq8@gmail.com

Hi Guys, I''m playing with Blade 6300 to check performance of compressed ZFS with Oracle database. After some really simple tests I noticed that default (well, not really default, some patches applied, but definitely noone bother to tweak disk subsystem or something else) installation of S10U3 is actually faster than S10U4, and a lot faster. Actually it''s even faster on

On Solaris 10 If I install using ZFS root on only one drive is there a way to add another drive as a mirror later? Sorry if this was discussed already. I searched the archives and couldn''t find the answer. Thank you.

Hi All, Two and three-node clusters with SC3.2 and S10u3 (120011-14). If a node is rebooted when using SCSI3-PGR the node is not able to take the zpool by HAStoragePlus due to reservation conflict. SCSI2-PGRE is okay. Using the same SAN-LUN:s in a metaset (SVM) and HAStoragePlus works okay with PGR and PGRE. (both SMI and EFI-labled disks) If using scshutdown and restart all nodes then it will
