Ext3, Ext4, any filesystem that you like. > Also, does btrfs have error detection or correction without using raid? By default a BTRFS filesystem will use RAID-1 for metadata on a single device by writing the data to two blocks. So a failure that results in one metadata block becoming corrupt or unreadable will result in the other being read. But if a data block becomes corrupt then you lose. You can configure BTRFS to use RAID-1 for data on a single device in theory at least, but last time I tried it the mkfs program didn't want to do that. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
