Slow Parity Speed

100 mb/s

Do you mean Mbits or MBytes?

  • Community Expert

Mb/s = Megabits per second

MB/s = Megabytes per second

lowercase m typically means 1000 and isn't often used in this context.

  • Community Expert

Are you writing to the parity array or the cache pool?

  • Author

MB/sec

And it's my parity check speed

  • Community Expert

Seems like a reasonable speed since it is having to write corrections to parity.

But the number of sync errors seems high for unclean shutdown, makes me wonder if parity was valid.

Both are OK, that's not the issue.

Can you see if there are any drive errors that aren't showing in the GUI? I've tried looking through the logs but didn't see anything.

I cancelled the parity check that was correcting errors and started a new one with only detection and there's a lot less sync errors showing up compared to yesterday.

Sync errors detected: 14

Those yesterday were already corrected. You might as well go ahead and correct the others.

I think those showing up in the GUI are the same ones that are logged. UDMA CRC errors logged by the disk might not show up either place since the data is resent.

Didn't see any other issues logged. You can run the diskspeed container to try and confirm all the disks are performing normally.
