Hello Unraid,

 

I checked my dashboard daily, today, I had some skipping on some playback of a media file and I checked my dashboard, and it looks like this:

 

 

I don't really understand how 14 drives could all go bad at once. Any insight, or help on this issue would be greatly appreciated.

 

My syslog and smart reports are attached.

 

I am running unRAID 6.1.6

 

Thank You

Without even looking at your reports, I can almost guarantee that they are going to be pretty much all Attribute 188 - Command Time-Out.

 

Seagate Drives report this attribute differently than how the UI was programmed to expect, and this isn't an issue.  Just go to Settings / Disk Settings and disable monitoring of attribute 188.

Hello Squid,

 

You are correct most of them are a 188 timeout, however I am also experiencing other issues on the following drives:

 

Disk 3 - Reported Uncorrect

Disk 11 - End-To-End Error

 

Thank You

there appears to be a problem with the zip file you attached - I cannot extract any of the contained files (although I can see their names).

The attribute 184 (end-to-end error) on your disk 11 has a status "failing now", which is the reason why it is displayed as a warning (=need your attention) on the dashboard.

 

According to the SMART WIKI attribute 184 means the following:

This attribute is a part of Hewlett-Packard's SMART IV technology, as well as part of other vendors' IO Error Detection and Correction schemas, and it contains a count of parity errors which occur in the data path to the media via the drive's cache RAM.

 

This sounds like a bad connection (cabling issue?).

No...  Its an INTERNAL fault to the drive.  SMART is set up so that a single failure will throw the drive into failing now status.

 

If you do not know the exact circumstances as to when and how the drive got it, then you should immediately RMA them.  (I have a drive that has one, but I do know exactly how and when that error popped up, so I've chosen to ignore it and merely keep an eye on it (the drive is out of warranty)

Thanks guys! I will replace both drives. Ill have to do one at a time though, I think I am going to replace the one that says it has an uncorrectable error first. Really appreciate the help, unRAID has an awesome community!
