Dear all,
I have tried searching the forum, but could not find a solution to my problem.
I have this strange issue that my write speed drops to very low numbers ~700kb/s. Read speed is still normal ~112mb/s saturating my 1gbit link.
Strangely if i reboot the server. Both write / read speed is normal again at 112mb/s, but after a while (normally a couple of days) issue of slow write speed comes back.
I tried scrubbing the pool couple of times with zero errors
I also did long SMART tests on all drives, all is ok
Any thoughts on what other troubleshooting steps I could take?
My hardware:
