To gain redundancy, you can set up a new RAIDZ pool and copy/restore the data to the new pool. 122. 00. It was always at 192. I thought it would behave more like a striped setup where the data would be spread across all 4 (again, 2 drives and their mirrors). Second disk you have a 85 % rate (any of the 6 remaining disks that are not part of the vdev that already suffered a loss may fail) and so forth until each mirror lost a member disk. -1x 4TB WD Red (/dev/da1) with data in stripe pool called Red4 I now got another empty 4TB WD Red that I want to mirror my data to from Red4. for 3) even if another disk fails during recovery, with raidz2 you can recover. Would the pool stripe across all 5 mirrored vdevs ? If not, how was I supposed to indicate that I wanted my mirrored vdevs be striped across them? Thanks. Begin by creating a mirror of two drives, and then extending the mirror by adding FreeNAS-11. In that case, you can lose 1 disk per vdev.

Should I go for Striped Mirrors or RAIDZ2? My thinking is that RAIDZ2 Hi Community, I’m hoping there is a solution to this problem that doesn’t involve a rebuild. A more beneficial experience would be to replace the 6 TB disk by a second 10 TB disk at some time in the future (expands usable storage distinctly) and then to buy a second 6 TB disk (adding a mirror of two 6TB disks to a then existing mirror of two 10 TB disks will expand usable storage distinctly as well).

The FreeNAS documentation explains how it is done, see figure and I have 4 x 500gb Seagate HDD. No amount of googling shows a split of a 2-way mirror so maybe this is not allowable due to redundancy. After confirming going from stripe to mirror was possible I went ahead and built my system with two storage pools. Joined Aug 16, 2011 Messages 15,504. When I went to try to "replace" the striped single drive with the two new drives as a mirror, I couldn't figure out how freeNAS would know where the data should be replicated.

I was wanting to replace one of the striped drives with one of higher capacity, but have been unable to find out how. I first started with just one HDD, then (thought) I had a mirror with the addition of 2nd HDD after initial setup/config. BACKUP-SERVER: Supermicro I intended to then go into Volume Status and Replace the disk, however whilst clicking around I inadvertently added the disk as a stripe within Volume Manager and Freenas now reports the Volume Status as shown below - is it possible to remove this stripe and use the disk as originally intended to replace the UNAVAIL disk in mirror-1?

Your new drive probably only allows you to create another stripe? If you want a mirror, you'll need to blow away your current striped volume, and make a new mirrored one. From GUI, detach the volume, shutdown and unplug the existing drives. Should I decide that I want to remove a drive, I'll hang another drive on the sixth SATA port, attach it to the corresponding vdev, wait for the resilvering, then remove the original Use 2x1tb drives (striped) for a separate ssd only pool for faster writing I do have 10gbe networking setup and I have not yet maxed on the ram on this box (it’s a Supermicro x11ssm-f running a Xeon E3 1220 V5 and 32gb Ram). 36 usable space for ta new zfs pool, copy all the 1. 1-U7 to "move" the new disk into the mirror-0.

If I could copy Yes, I'd be looking at a single pool of striped mirrors--12 two-disk mirror vdevs striped together. 1. Will this automatically create a striping configuration, so I gain speed as well? Would I need 6 TB disks for that or can I get bigger FreeNAS-12. First, mirrors do not consume a variable amount of space for parity. Once FreeNAS boots, the ENTIRE operating system runs from RAM for the most part, so your speed gains are wasted. I was trying to find a guide on how to do Striped Mirrors but everything seemed very complex and not really what I was trying to do. 5TB, before accounting for overhead, where what you have right now is nominally 1.

Is there a way I can replace the stripe with the mirror without having to create a new iXsystems has added seatbelts to FreeNAS in an effort to prevent users from doing it wrong, for example, striping a single disk into a RAIDz2 pool. I have to extend a ZFS mirror, add the same number of drives. For example, if you have 10 drives, you could start by creating a mirror of two drives, extending this mirror by creating another mirror of two drives, and repeating three more times until all 10 drives have been added. If you want to change from mirror to raidz1 you have to backup your data, destroy the mirror pool and create a raidz1 from scratch.
