That's just about So what do you do if your mythical file system supports bad block relocation but doesn't support something else you need, like journaling or quotas or whatever? Nobody's mentioned the most obvious reason why it doesn't belong in the filesystem, but needs to be in something like the 'md' layer like (I think) John Bradford suggested: No amount of code wanking in the filesystem is going to save you if you hit an error on your swap partition - but an 'md'-like driver might be able to save you. --==_Exmh_-1671983278P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQE+o/y7cC3lWbTT17ARAmJRAJ9wROT130q6knXVgzZ3OWPA5dpGigCgkcpr ef+M5vWUBQCHwrNMxFfxt90= =vZso -----END PGP SIGNATURE----- --==_Exmh_-1671983278P--
