2014年10月7日 · Then I read about ZFS's superior implementation of RAID5, so I thought I might even get up to 2TB more usable space in the bargain using RAIDZ-1. However, I keep reading …

However, ZFS also provides ARC/L2ARC, compression, snapshots, clones, and various other improvements that you might also want, and in that case, perhaps it is still your filesystem of …

I'm planning on building a file server using OpenSolaris and ZFS that will provide two primary services - be an iSCSI target for XenServer virtual machines & be a general home file server. …

2014年4月24日 · zpool status -v is the correct way to understand what a ZFS pool is comprised of. A better example, as the vdev groups are enumerated, beginning with 0. A better example, …

2013年9月6日 · Datasets are not constrained to one vdev, their data is stored wherever ZFS can find in the pool to put it. This is the main concept of 'pooled' storage. The zpool merges X …

So really the only question here is raidz (raidz1) or mirror. And then you're back into the more familiar world of data resiliency versus capacity. A 3-way mirror is significantly more resilient …

I typically go with striped mirrors (RAID 1+0) on my ZFS installations. The same concept applies. More mirrored pairs == better performance. In ZFS, you can only expand in units of a full vdev. …

2020年1月30日 · I tried with a VM doing: zpool detach DATARAID sdc DATARAID has now one disk, no mirror, nothing And then: zpool add DATARAID raidz sdc sdd -f (-f because sdc has …

+1 Also, the perblock checksums allows ZFS, should it find corruption in an array, to single out the affected files. Most R5 HBAs will simply mark the whole volume as corrupted, or report back to …

As for expanding there are a number of options of how to grow your ZFS 5x3TB raidz pool: Add a mirror VDEV (pairs of disks) pool spans the two VDEVs (12TB raidz & 3TB mirror). Add a raidz …
