I had a parity check that had been stuck at 100% for quite some time earlier this month. Here is a screenshot I took from when that was occurring:

 

 

From my syslog it looked like the following was happening roughly every 5 minutes.

I shut my server down, re-seated my HBAs, re-seated all my cables, and restarted my server.

 

The issue persists. Attached are diagnostics files pre and post-reboot for review (in case anything has changed).

 

I'm not sure what is causing this issue and was hoping I could gain some guidance from the forum.

 

I have another parity check running currently, but I expect it to get to 100% and stall again.

 

Thanks in advance for any help you guys can provide.

Known issue with the Dell H700, note that RAID controllers are not recommended in general, but this one has this particular extra problem.

@JorgeB I appreciate the reply. I hadn't noticed it having the issue previously. My parity checks always used to finish.

 

I had some followup questions.

 

1. Can I get parity checks to finish? (Is there a workaround)

2. Can I validate that parity is valid by it just getting to 100% (In case I need to rebuild a drive)

3. If there are NO workarounds and parity will never be valid, what's our most supported HBA presently? I'll spend money for good support. And what's my best guide on rebuilding the array? Can you shoot me a link to the article I need to keep my current data intact? I'll make it work over a vacation of mine.

Not as far as I know.

Should be valid, IIRC it stops 128 sectors from the end, so there should be nothing important there.

But note that changing from a RAID controller to a HBA is usually not plug and play, i.e., the disks may not mount, one of the reasons RAID controllers are note recommended.

Regarding the plug and play, that's okay.

 

Half my array is presently empty. I'll find a way to make this work.

 

I appreciate the feedback.
