You mention: * dump process frequently hangs In my case, the dump was progressing normally. The _rest_ of the system was hung. * UFS2 snapshot generation (mksnap_ffs, dump -L) takes too long; system is = unusable during this time In my case, snapshot creation took ~4 minutes. The system was running normally for 2.6 hours after snapshot creation completed before it froze. * Filesystems not cleanly shut down if reboot performed while dump(8) still= running Not applicable. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --IU5/I01NYhRvwH70 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkj1sMMACgkQ/opHv/APuIe6cwCeJdYvfpQdOzTdQQNB2g+ioKk+ JtgAn050P0w/T2iWYh11Q0AppKtOY4+3 =LmFS -----END PGP SIGNATURE----- --IU5/I01NYhRvwH70--
