Hi, folks, testing zfs. I'd created a zpoolz2, ran a large backup onto it. Then I pulled one drive (11-drive, one hot spare pool), and it resilvered with the hot spare. zpool status -x shows me state: DEGRADED status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to co...

The ZFS-on-Linux (ZoL) code has been stable for years. In recent months, the BSDs have rebased their offerings from Illumos to ZoL. The macOS port, called O3X, is also mostly based on ZoL. That leaves

...3 years (i used to have to update and rebuild the drivers), anything LSI based, which includes Dell PERC, have been pretty good. The newer models do even better at doing the right thing. 2. ZFS seems to be ok, though we were testing it with an Ubuntu system just a month or so ago. Note: ZFS with a zpoolZ2 - the equivalent of RAID 6, which we set up using the LSI card set to JBOD - took about 3 days and 8 hours for backing up a large project, while the same o/s, but with xfs on an LSI-hardware RAID 6, took about 10 hours less. Hardware RAID is faster. 3. Being in the middle of going through three da...
