Potential Storage Spaces Issue?

Recommended Posts

I use storage spaces. Its in a usb3 connected box. I have 3x2TB Red drives (for the server pool) and 1x2TB Regular drive (for server backups as it can't backup to the pool).

 

No problems at all so far but its only been a couple weeks.

 

I do however also backup everything monthly to another drive that I leave disconnected just in case.

Been seriously working with Storage Spaces with live data for the past few weeks -- I haven't been that impressed with parity (at least for my needs) but I am impressed with 2-way Mirror using ST3000DM001's -- I'm getting speeds comparable to a regular Mirror set up in Computer Management which is very similar to a stand alone ST3000DM001. No problems that I've found yet though I plan to bang it around for some time.

I have read positive reviews in regard to the two way mirroring. That will be the way I go for now. Parity can wait until they can fix whatever bugs it may have. I will keep the storage folders in the mirror including client backups.

I posted my performance test's here

Grear writeup! How did you post it as a blog entry? I'd like to do something similar.

 

I believe you either have to PM Dave or have been granted the right to post blog entries on HSS.

OK so I haven't been around here in awhile...sorry about that. I've been working on a new release of WindowSMART 2013 and Home Server SMART 2013, plus I'm working on rebuilding my website from the ground up. Throw in a prototype and proposal to a big company for WindowSMART and I come to realize I need longer days!

 

Anyhow, I have a problem with Storage Spaces on my HP MediaSmart EX487. The processor's been upgraded to an E5300, plus 4 GB of RAM (did that all last year). When I rebuilt to 2012 Essentials, I installed an Intel 160GB SSD into the first slot, so the OS runs off the SSD. It is so fast. Then each bay of the server has either a 1 or 2TB HDD, plus 3 x 2TB USB HDDs and a 1TB HDD on eSATA.

 

All of the hard drives I lumped together into one big Storage Space, and then provisioned a big D: drive and that's where Essentials puts all of the server folders, including backups.

 

At least once, but sometimes several times, per day, I'll notice critical alerts--backup service is not running, folders are missing, etc. When I log into the server, the D: drive is gone. The fix is to pull up Server Manager, bring up Storage Spaces, detach the virtual disk and then reattach it.

 

I've got Home Server SMART 2013 installed, and the disks are all healthy. One disk has a few bad sectors, but those bad sectors took up residence on the disk long before Server 2012 Essentials was installed.

 

Normally if you have a disk cutting in and out, perhaps because of a bad data cable, you'd see errors and warnings like crazy in the System and/or Application event logs. Nary a one. I've combed through all of the event logs I can find; there's even an event log for storage spaces. I don't see any problems there either. Nothing in Home Server SMART's logs suggest a disk cutting out, and Storage Spaces doesn't show disks dropping offline either. And since the storage pool has redundancy enabled, even if a disk did cut out, the virtual disk shouldn't disappear!

 

My other MediaSmart Server, an EX490 with otherwise identical hardware (E5300, 4GB and an OCZ Vertex4 SSD), has three different Storage Spaces. One mirrors a pair of 2TB USB drives, a second pools 4 x 2TB Hitachi Deathstars and the third is a couple of the hard drives in the EX490's chassis. With the exception of a bad eSATA cable, I've never had any trouble with those storage spaces. (Note this one is using full-blown Windows Server 2012, not Essentials.)

 

The only thing in 2012 Essentials that caught my eye was a warning that the backup database cleanup hasn't run successfully in over 30 days. There's a "try to repair" link, that when clicked, appeared to kick off the task. The storage space will drop off within an hour of doing that. I'm not sure if it's coincidence...I'm hard-pressed to believe that the backup cleanup would cause a virtual disk to dismount.

 

Anyone else seen this?
