I tried to mound datasets manually - system became thinking= on /home and /usr. Can you run "iostat -x 1" while while youre zfs mount -a hangs? It will probably indicate that there is 100% disk utilization on the disk in question, indicating there is one or more I/O request(s) outstanding to the device, indicating a driver/controller/cabling/drive problem. If on the other hand 'zfs mount -a' hangs but there is no ongoing attempts at disk I/O according to iostat, there may be a software problem with zfs or something else, although since you have confirmed disk-related issues it might have been triggered by actual on-disk corruption. --=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --/04w6evG8XlLl3ft Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEARECAAYFAkmtRLsACgkQDNor2+l1i32sbgCglO+8joRcW8pelP/899h2vio/ nDMAoKQjjZ2gbw7Df/y4ansSfX/SFfCO =56YR -----END PGP SIGNATURE----- --/04w6evG8XlLl3ft--
