Freezes on reads could be a symptom of a bad (unreadable, or very slowly readable - which is worse) sector, perhaps it could be detected= by the SMART test. Or also do a full read of the drive directly (not through t= he RAID) e.g. with "badblocks" and see if you get any I/O errors that way. --=20 With respect, Roman --Sig_/ytUbQ8vIvGp.HF=XAtmdnOk Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk3yW6AACgkQTLKSvz+PZwi/kACdFYyH5e2uH0Y7AZYhWfaBJ9+j mkkAn2VjKpkCcjuNbNr58DEskyMDKzDx =ABrf -----END PGP SIGNATURE----- --Sig_/ytUbQ8vIvGp.HF=XAtmdnOk--
