Hi all, I recently purchased 7 HGST 4TB SAS drives after discovering @BLinux thread in "Great deals". I need six for my zpool, but bought one extra.
I’ve used them to upgrade my Dell R710 from 2TB SATA to these 4TB SAS. I run a OmniOS VM with the SAS controller passed through. All the drives are in a single raidZ2 zpool.
A few of the drives have issues:
The way I’ve tried to test and verify the drives is by:
The drive with the most errors (SN: K4HGL6ZB) returned a bunch of errors after resilvering. I pulled it, and used another drive, then later I tested it in another slot. This time the resilvering went fine. It also passes a long S.M.A.R.T test. Could it be that it was a bad seating of the drive bay?
Drive info:
(I’m putting the ones with errors first)
My main questions to you guys is:
Based on this info, which of these drives could I trust (and which should I return/exchange)?
(On a side note. I’m in the EU and the seller in the US, so the shipping is quite expensive. The heavier/larger package, the more expensive, etc.)
I don’t have too much experience from buying “used” drives, so all input/advice is much appreciated!
I’ve used them to upgrade my Dell R710 from 2TB SATA to these 4TB SAS. I run a OmniOS VM with the SAS controller passed through. All the drives are in a single raidZ2 zpool.
A few of the drives have issues:
- One drive that seems to work-ish, but refuses to complete the long S.M.A.R.T test. (I've pulled that one)
- One drive that shows quite a few errors, but seems to have stabilized.
- Two drives with few “errors”.
- (Please see below for all the disk data.)
The way I’ve tried to test and verify the drives is by:
- Pulling the existing 2TB SATA drive and replacing them with the 4TB drive. That forces a resilvering that took around 10 hours.
- Run long S.M.A.R.T tests.
- Multiple regular scrubs.
- Fill the zpool with semi random data and then verify it again via this “disk-filltest” script (took around ~30 hours)
- Run a full scrub with no erros (~30 hours), but the S.M.A.R.T threw an error on one drive (not sure how bad they are?):
