I can confirm this behavior, I have several X4540's, 48x 1TB disks, running 2008.11 snv_106 Destroying large filesystems, or filesystems with a lot of snapshots will take an exceedingly long time. During the destroy, I see only about 1MB/sec of I/O (reads and writes). Luckily, I don't destroy very often. -- Brent Jones br...@servuhome.net _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
