Hi,
My OmniOS host is expreiencing slow zfs writes ( around 30 times slower ).
iostat reports below error though pool is healthy. This is happening in
past 4 days though no change was done to system. Is the hard disks faulty ?

Hello,
I'n updating Devilator, the performance data collector for Orca and FreeBSD to
include ZFS monitoring. So far I am graphing the ARC and L2ARC size, L2ARC
writes and reads, and several hit/misses data pairs.
Any suggestions to improve it? What other variables can be interesting?

Yes, thanks :) I think I will add them, I just started with the esoteric ones.

were two Vdev with 24 disks ( disk 0-23 ) for close to year. After which
which we added 24 more disks and created additional vdevs. The initial
vdevs are filled up and so write speed declined. Now how to find files

Anyone knows if there is any progress on bp_rewrite ? Its much awaited to
solve re-distribution issue, and moving vdevs.
Regards,
Ram
