https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211381 --- Comment #4 from braddeicide@hotmail.com --- Yes I was suspicious of the script when I removed and readded the device and it worked for a while, but the script kept saying degraded. How I can tell it's gone wrong again however is in zpool iostat -v when all data is dropped from the arc and capacity stays 100% free despite writes. # dtrace -n 'sdt:::l2arc-iodone /args[0]->io_error != 0/ { printf("io_error = %d", args[0]->io_error); }' dtrace: description 'sdt:::l2arc-iodone ' matched 1 probe dtrace: buffer size lowered to 512k CPU ID FUNCTION:NAME 0 57400 none:l2arc-iodone io_error = 22 3 57400 none:l2arc-iodone io_error = 22 1 57400 none:l2arc-iodone io_error = 22 1 57400 none:l2arc-iodone io_error = 22 1 57400 none:l2arc-iodone io_error = 22 3 57400 none:l2arc-iodone io_error = 22 3 57400 none:l2arc-iodone io_error = 22 3 57400 none:l2arc-iodone io_error = 22 1 57400 none:l2arc-iodone io_error = 22 3 57400 none:l2arc-iodone io_error = 22 0 57400 none:l2arc-iodone io_error = 22 1 57400 none:l2arc-iodone io_error = 22 0 57400 none:l2arc-iodone io_error = 22 2 57400 none:l2arc-iodone io_error = 22 -- You are receiving this mail because: You are the assignee for the bug.home | help
