So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

So I have attached to my system two 7-disk SCSI arrays, each of 18.2 GB disks. Each of them is a RAID-Z1 zpool. I had a disk I thought was a dud, so I pulled the fifth disk in my array and put the dud in. Sure enough, Solaris started spitting errors like there was no tomorrow in dmesg, and wouldn''t use the disk. Ah well. Remove it, put the original back in - hey, Solaris still thinks

Hi all! I got a short question regarding data migration: I want to copy my data (~2TB) from an old machine to a new machine with a new raidz1 (6 disks x 1,5TB each ). Unfortunately this is not working properly via network due to various (driver) problems on the old machine. So my idea was: to borrow one disk from the new raidz1 (leaving the raid in degraded, but working status) attach the now

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 > >

Hi all, I recently created a RAID-Z1 pool out of a set of 7 SCSI disks, using the following command: # zpool create magicant raidz c5t0d0 c5t1d0 c5t2d0 c5t3d0 c5t4d0 c5t5d0 c5t6d0 It worked fine, but I was slightly confused by the size yield (99 GB vs the 116 GB I had on my other RAID-Z1 pool of same-sized disks). I thought one of the disks might have been to blame, so I tried swapping it out

Hello All, I have a zpool that consists of 2 raidz vdevs (raidz1-0 and raidz1-1). The first vdev is 4 1.5TB drives. The second was 4 500GB drives. I replaced the 4 500GB drives with 4 3TB drives. I replaced one at time, and resilvered each. Now the process is complete, I expected to have an extra 10TB (4*2.5TB) of raw space, but it''s still the same amount of space. I did an export and

Hi all, Sorry for the newbie question, but I''ve looked at the docs and haven''t been able to find an answer for this. I''m working with a system where the pool has already been configured and want to determine what the configuration is. I had thought that''d be with zpool status -v <poolname>, but it doesn''t seem to agree with the

Hi, Well I have a freshly built system with ZFS raidz. Intel P4 2.4 Ghz 1GB Ram Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (2) Intel Dual Port 1Gbit nics I have (5) 300GB disks in a Raidz1 with Zfs. I''ve created a couple of FS on this. /export/downloads /export/music /export/musicraw I''ve shared these out as well. First with ZFS ''zfs

Hello everyone, As one of the steps of improving my ZFS home fileserver (snv_134) I wanted to replace a 1TB disk with a newer one of the same vendor/model/size because this new one has 64MB cache vs. 16MB in the previous one. The removed disk will be use for backups, so I thought it''s better off to have a 64MB cache disk in the on-line pool than in the backup set sitting off-line all

Hi there, i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid. Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity. (i have only one another 1 tb disk to backup the files) Thank you for you replies and

I made a bad judgment and now my raidz pool is corrupted. I have a raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7 and tried to add my pool to freenas. After adding the zfs disk, vdev and pool. I decided to back out and went back to opensolaris. Now my raidz pool will not mount and got the following errors. Hope someone expert can help me recover from this error.

Hi, My swap is on raidz1. Df -k and swap -l are showing almost no usage of swap, while zfs list and zpool list are showing me 96% capacity. Which should i believe? Justin # df -hk Filesystem size used avail capacity Mounted on /dev/dsk/c3t0d0s1 14G 4.0G 10G 28% / /devices 0K 0K 0K 0% /devices ctfs

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

Hi list, My zfs write performance is poor and need your help. I create zpool with 2 raidz1. When the space is to be used up, I add 2 another raidz1 to extend the zpool. After some days, the zpool is almost full, I remove some old data. But now, as show below, the first 2 raidz1 vdev usage is about 78% and the last 2 raidz1 vdev usage is about 93%. I have line in /etc/system set

I created snapshot for my whole zpool (zfs version 3): zfs snapshot -r tank@`date +%F_%T` then trid to send it to the remote host: zfs send tank at 2008-07-25_09:31:03 | ssh user at 10.0.1.14 -i identitykey ''zfs receive tank/tankbackup'' but got the error "zfs: command not found" since user is not superuser, even though it is in the root group. I found

Hi all, Please can you help with my ZFS troubles: I currently have 3 x 400 GB Seagate NL35''s and a 500 GB Samsung Spinpoint in a RAIDZ array that I wish to expand by systematically replacing each drive with a 750 GB Western Digital Caviar. After failing miserably, I''d like to start from scratch again if possible. When I last tried, the replace command hung for an age, network

Hi, I was first attracted to ZFS (and therefore OpenSolaris) because I thought that ZFS allowed the used of different sized disks in raidz pools without wasted disk space. Further research has confirmed that this isn''t possible--by default. I have seen a little bit of documentation around using ZFS with slices. I think this might be the answer, but I would like to be sure what the

Hello, 1) If i create a raidz2 pool on some disks, start to use it, then the disks'' controllers change. What will happen to my zpool? Will it be lost or is there some disk tagging which allows zfs to recognise the disks? 2) if i create a raidz2 on 3 HDs, do i have any resilience? If any one of those drives fails, do i loose everything? I''ve got one such pool and

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, I''m completely new to Solaris, but have managed to bumble through installing it to a single disk, creating an additional 3 disk RAIDZ array and then copying over data from a separate NTFS formatted disk onto the array using NTFS-3G. However, the single disk that was used for the OS installation has since died (it was very old) and I have had to reinstall 2008.11 from scratch onto a
