Intermittent Copying From Array to Cache?

Featured Replies

I was doing some maintenance on my Cache drive so I backed it up and now need to restore some of the files.

 

For some reason, at least through Windows Explorer (I've experienced these issues in the past as well), copying speeds start at 30-40MB/s, and within 15 seconds drop to 0.  They'll stay at 0 for a few seconds and perk back up to 4-6 MB/s.  Then back to 0 where it sits for an arbitrary amount of time.

 

Any idea what could be causing this?  I imagine this is not normal behavior.  Is there a certain log I should look into to better understand why this may be happening?

Here's the diagnostic file.  I'm currently copying a file and it has been about an hour (currently 72%) for a 50 GB file.  It is the docker.img file.

There are no obvious error messages showing up in the syslog and SMART report for all drives looks fine, so some of the obvious culprits are not your problem :)

 

You mention you are copying the docker.img file.    However according to the log docker is already started!  I would only expect your to be copying that file with docker stopped.

 

There are also a number of messages about /etc/libvirt not being mounted - I expect this is because you have not enabled VM support in the Settings?

 

As a final comment it looks like the cache disk is in reiserfs format?  This can perform slowly when creating new files if the disks gets anywhere near full.  The recommendation is to use XFS for the cache disk if it is a single disk, and BTRFS if it is a cache pool (forced in such a case).

Have switched to XFS.

 

Am now copying a few files over.

 

Transfer speeds of 108 MB/s and steady!

 

Thanks for the help and advice.
