I have a HomeAssistant VM that often gets put into a "Paused" state meaning that all of my home automation ceases to work. I cannot figure out the likely cause of the pausing as my cache drive seems to have plenty of room. It started happening about 3 weeks ago and I made a big effort to watch cache usage but it is still happening.

 

Attached is my diagnostics zip and below is some info I think may be relevant, I would really appreciate any help!!

 

On my unRAID server:

Thanks again for any help!

Paused is correct term rather that Suspended

Cache needs a balance to reclaim unallocated space, see here:

https://lime-technology.com/forums/topic/62230-out-of-space-errors-on-cache-drive/?do=findComment&comment=610551

I will try that right away!

Thanks so much.

 

I will report back after a few days/week whether problem is fixed with about command.

According to that post you linked it was to be fixed in kernel 4.14. Seeing as I am on unRAID 6.6.6 and running kernel 4.18 why it is still a problem?

 

root@Tower:~# uname -a
Linux Tower 4.18.20-unRAID #1 SMP Fri Nov 23 11:38:16 PST 2018 x86_64 Intel(R) Xeon(R) CPU X5675  @ 3.07GHz GenuineIntel GNU/Linux

It is fixed, but if your cache was created on an older kernel and never balanced once you got on >4.14 you can still run into this, after this balance it should't happen anymore.

Marking this as solved!

 

No problems since, Thanks a million johnnie.black!
