But the dump started this restore will emit a warning if dump writes a stream that is out of order=20 because of a live file system but that is not what you are seeing. > morning is still hanging (in sbwait) -- I've never seen this before.

I've never had dump fail but it IS rather crusty and slow.. That said tar=20 doesn't cover all the information I believe. =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart1370125.q0FYTSpdyJ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iD8DBQBJyZCj5ZPcIHs/zowRAuC5AKCsG52ocLa5Mw5KyHhhCsCQaLVgTwCfQgIX sNG6y1F8aM8Ge4/yK1uMyDc= =bb2i -----END PGP SIGNATURE----- --nextPart1370125.q0FYTSpdyJ--
