first post so lets hope i get this right

i recently set up unraid and for about a week everything was going great and now its slow and unresponsive and i have to reboot once a day to make it usable for about 15 mins and for the life of me i cant figure this out

specs are dual xeon E-5 2660 v2, 16gb ecc ram (upgrade is coming) 3x8tb and 5x4tb drives 256gb cache drive

Parity and disk1 have dropped offline. Check all connections power and SATA on all disks and post another diagnostic.

ok i wiggled all the sata cables and power cables i will keep you posted

You're using a 2 port controller with two SATA multipliers, those kind of timeout issues are normal with those, I recommend you get an LSI HBA instead or you'll have constant issues.

so you are saying i need a sas controller, i did wiggle all the sata data cables and power cables seemed to work for a while and came back to screeching crawl

You need a decent HBA, port multipliers will generally be nothing but trouble, get any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.

 

 

ok thanks for the info i just dont understand why this is a problem now have been running this setup for about a year without any issues

I'm not saying the controller is the source of all your problems, but if you keep getting timeout errors similar to those on the diags you posted, the server will be unresponsive during those, and port multipliers are known to cause that.

i wont argue with an expert so i have ordered a sas controller per your specifications and cables lets hope that fixes it

i put the lsi 9211-8i in and it worked liek charm its completely different
