Hi, Sorry for the late response, but you may also eneble vdev prefetch to incre= ase the speed of resilver: sysctl vfs.zfs.vdev.cache.size Some say this speeds up the process :) Regards, Ivailo Tanusheff -----Original Message----- From: owner-freebsd-fs@freebsd.org [mailto:owner-freebsd-fs@freebsd.org] On= Behalf Of mxb Sent: Friday, July 05, 2013 10:38 PM To: Steven Hartland Cc: freebsd-fs@freebsd.org Subject: Re: Slow resilvering with mirrored ZIL Thanks everyone for a very good info provided in this discussion! Question is if I should wait for resilvering to finish? It runs at 97B/s no= w. Do I have any other options in this situation? Put back old disk? I really don't want to lose all data on this pool. //mxb
