Still experimenting with ZFS on a new server with proxmox 3.4. Current Setup
BOOT: - Intel SSD 535 - ZFS Data ZFS: - 4 * WD Velocoraptor 600GB Drives - SSD for SLOG and Cace - ZIL capped at 4GB It runs ok for a couple of days and then ZFS seems to go nuts. IO delays goes over 50% until I kill the one VM that runs off the ZFS pool. the whole system is then incredibly slow to use - ssh login takes 10-20 seconds. pveperf on the boot disk shows the following: CPU BOGOMIPS: 140548.16 REGEX/SECOND: 972975 HD SIZE: 92.78 GB (rpool/ROOT/pve-1) FSYNCS/SECOND: 10.00 DNS EXT: 126.03 ms DNS INT: 22.12 ms (brian.softlog) Truly terrible fsync. The data pool is the same. The only cure seems to be a reboot. Server has 64GB RAM and Dual Intel E5-2660 -- Lindsay
