I'm looking for some advice on a cheap solution for fast(ish) storage for VMs. I was thinking of using 2 x 1TB Samsung 860 Evo in an MDADM RAID 1 setup on Linux. Since I will be sharing out this storage as ISCSI for ESXI (i.e. it will be a big chunk of storage shared out, not individual files...

anybody know how to get rid of this? :confused: It's set up a 'performance optimization' task to run every afternoon. Obviously not ideal! I have a delete option next to the one I set up, but not the stupid daily one. How do I get rid of/change the time of that?! Obviously being Samsung, it is...

Running the drives using the IT mode firmware and correctly aligned partitioned gets about 100mb/s seq writes back. Same drives, with IR mode firmware get only 44mb/s seq writes. So how do I go about aligning the partitions properly when using RAID? My guess would be that the RAID controller...

I have a system with this card in, but the writes are very slow: (This is the best it has done, sector size override and queue length have been tuned to the optimal settings through trial and error with ZFSGuru benchmarking). Google research indicates the slow writes may be down to a lack of...

Has anybody got a good solution for monitoring FreeNAS? We use Nagios to monitor our other hosts, but can't seem to get anything other that a few basic checks done for FreeNAS. The SNMP doesn't seem to output much of use, and the alerting system seems to only display a red or green light...

Looking for an extendible RAID type system for home use (storing BR rips, photos, music and so on). What I want to do is start with two x 2tb discs, then add a third ... up to a total of 5 discs. Ideally without deleting/restoring any data. The other factor is CPU usage, I'll be using an Atom...

Got a Zpool with 5 mirrored pairs of 2tb SATA disks and 2 hot spares. No errors, all working, but a bit slower than expected. Anyway when checking out the iostats we see the following: extended device statistics device r/s w/s Mr/s Mw/s wait actv svc_t %w %b...

Is it expected that ZFS/Nexenta performance will be absolutely dire on SmartArray P400 hardware? For example P400 card, mirrored pair of 5400rpm SATA discs, (for testing only before purchasing faster discs) writing at only 2.9mb/s (expect at least 40mb/s): We've tried changing MAX/MIN...
