Hi folks,

 

I'm at a loss. I have an unmaintained (fas2020) 7-mode HA pair in a site that's slated to be decommed, but for now, I need to keep the lights on. There is a qtree snapmirror that, aside from Mondays, runs in about 3-4 hours. Mondays, it takes 2-4 days. The change rate on the source doesn't appear to be any different. Also, this was working happily for years and only started acting up lately. There are only 5 disks on the system, and while they're at 100% now, they're also at 100% during a sample taken while this context wasn't updating, and while it was updating in a way that finished in 4 hours.

 

So far, I've checked statit during the event and while idle, and I couldn't see anything that stuck out as a massive difference, except maybe name cache hits? I have 68% name cache hits during this transfer, and 100% while idle.

 

I don't see anything suspicious in the wafl scan status, and reallocate status -v shows:

 

Reallocation scans are on

No reallocation status.

 

CPU is idle, network has no errors. Does anyone have any suggestions? What kinds of things should I be looking at?

 

Thanks,

 

Basil
