Choosing a NAS?

[alsenior]

thats nuts. How can a 3 drive RAID 5 array get rates like that!

What switch are you using?

nothing special. i just have gobs of cpu and ram to throw at it.

i used

mdadm --create /dev/md1 --level=5 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1

i didnt even use the metadata flags or block size flags. everything is more of less defualt.

The mirror only shows as degraded after I've rebooted the VM.
You can only use the CLI to recover anything ZFS related. That then puts the GUI out of sync with what is actually happening.

What a waste of time....
Nexentastor 3.0.5 is out now but I can't be bothered to test it based on previous experience.

If I'm honest I'm considering a second microserver since I have a backdated payrise coming at the end of the month (27th), so I might do some further testing with Nexentastor: I'd really much rather have my VMs sitting on ZFS and might be tempted to have the current Microserver sat as second tier backup with the Samsung Ecogreen disks, and a new Microserver stuffed with WD Black Editions. I'm not exactly filled with confidence that FreeNAS will have fixed their messy iSCSI target setup in their gold release, but I *could* yet be tempted back to Nexenta if the disk dropouts have been fixed in 3.0.5.

We'll see, I guess.

Are they tests done over the network trough? Run hdparm on your QNAP and compare...

I must be glutton for punishment. I'm downloading Freenas 8.0 release right now

That supports ZFS I believe - wonder if you'll have the same challenges with it.

of course it could just be a layer 8 issue and Nexenta is actually quite stable

ZFS is the default storage used for FreeNAS 8

To be fair, I have *never* had a problem with ZFS. I have had problems with Linux RAID however. I am currently running Solaris 10 on Intel, however, so maybe that's why.

It could be but then again I'm not the only one having all of the same problems

I've been testing WS2008R2 software RAID and the MS iSCSI client v3.3 and it's been rock solid but performance is pretty poor. Windows relies on the hardware for any sort of speedup.

removing/adding disks on the fly is picked up fine, although I'ts required manual intervention to trigger the rebuild of degraded arrays.
