I created a raidz zpool and shares and now the OS is very slow. I timed it and I can get about eight seconds of use before I get ten seconds of a frozen screen. I can be doing anything or barely anything (moving the mouse an inch side to side repeatedly.) This makes the machine unusable. If I detach the SATA card that the raidz zpool is attached to everything is fine. The slowdown occurs regardless of the user that I login as (admin, reg user), and the speed up occurs only when the SATA card is removed. This leads me to believe that something is going on with the zpool. There are no files on the zpool (I don't have the patience for the constant freezing to copy files over to the zpool.)
The zpool is 4TB in size. I previously had the system up and running for a
week before I did something stupid and decided to start from scratch and
reinstall and recreate the zpool.
The "zpool status" command shows no errors with the zpool and iostat:
mediaz used 470k avail 5.44T read 0 write 0 bandwidth read 37 bandwidth write 44
How do I find what is accessing the zpool and stop it?
David
