I'm trying to do live filesystem backups to a hot-spare system with UFS2 snapshots. I create the snapshots with mksnap_ffs, mount them, and then rsync the data over to the hot spare over NFS. I can very reliably cause the system to hang on disk requests to certain filesystems, requiring a reboot. I can also get this to happen with dump's "-L" option, but have yet to experience it with background fscks. Has anyone experienced this, or know of a fix? -- -- Skylar Thompson (skylar@cs.earlham.edu) -- http://www.cs.earlham.edu/~skylar/ --------------enig2078B3F5AAE2943D5EF0B153 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCo4i6sc4yyULgN4YRAqw7AJ9dxhkRpP0wAqInWgHZygIs/o+qwACfTyWA bCR1k+6WNNGU9QCowmTeSCc= =CNbo -----END PGP SIGNATURE----- --------------enig2078B3F5AAE2943D5EF0B153--
