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 &quo...

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

Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be). A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file (''mkfile -n 2000G'') offlined after pool creation, I was able to start using my pool b...

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 zfs:me...

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that i...

I have a zpool of five 1.5TB disks in raidz1. They are on c?t?d?p0 devices - using the full disk, not any slice or partition, because the pool was created in zfs-fuse in linux and no partition tables were ever created. (for the full saga of my move from that to opensolaris, anyone who missed out on the fun can read the thread http://www.mail-...

I''m having a serious problem with a customer running a T2000 with ZFS configured as raidz1 with 4 disks, no spare. The machine is mostly a cyrus imap server and web application server to run the ajax app to email. Yesterday we had a heavy slow down. Tomcat runs smoothly, but the imap access is very slow, also through a direct imap client runnining on LAN PCs. We figured out that the 4th...

Here is what I have: DiskA - 160GB DiskB - 200GB DiskC - 250GB DiskD - 500GB DiskE - 500GB (I also have a separate 20GB disk that I will be booting from.)

Running a zpool scrub on our production pool is showing a scrub rate of about 400K/s. (When this pool was first set up we saw rates in the MB/s range during a scrub). Both zpool iostat and an iostat -Xn show lots of idle disk times, no above average service times, no abnormally high busy percentages. Load on the box is .59. 8 x 3GHz, 32GB ram, 96 spindles arranged into raidz zdevs on OI 147.

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''ve installed Open Solaris 2009.06 on a machine with 5 identical 1TB wd green drives to create a ZFS nas. The intended install is one drive dedicated to the OS and the remaining 4 drives in a raidz1 configuration. The install is working fine, but creating the raidz1 pool and rebooting is causing the machine report "Cannot find active partition" upon reboot. Below is command line output from the live cd during the install and post install. Note that I''ve tried this a few t...

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 free disk locally to the old machine create...

I suspect it''s probably not a good idea but I was wondering if someone could clarify the details. I have 4 250G SATA(150) disks and 1 250G PATA(133) disk. Would it cause problems if I created a raidz1 pool across all 5 drives? I know the PATA drive is slower so would it slow the access across the whole pool or just when accessing that disk? Thanks for your input. - Chris
