I like reiserfs, but I have been bitten by all types of filesystems. None is fully reliable. Currently I tend to use ext3 for the root partition, and reiserfs or xfs for data partitions. On single partition systems I use reiserfs with a separate boot as ext2.
Are you assuming that root partition is changing less then data partition? Or vise versa? That is, do you want ext3 to do more journaling or less? My impression from ext3 corruption was that it happened during one of ext3 hidden activities - disk has been working hard, though I did nothing at the time. Of course it does not prove anything, just my gut feeling. I think I should anyway reconsider my partitioning approach. ...
A root partition containing the system, not home, usually changes less, yes. Usually, because a lot of things get written to /var. The thing is, I trust a bit more ext3 recovery tools than reiserfs. I prefer having my system up, then recover data with system up. And, bugs related to reiserfs are not solved or very slowly (for instance, hibernation and restoring from reiser fails, blame grub)
I don't know why gparted says that. You could also try:
file -s /dev/sda7
Perhaps there is something at the start of the partition that "look" like reiserfs. I would backup all the data, then recreate the filesystem entirely (on those two partitions), by using "mkreiserfs" (don't forget to add a label).
I guess, this is because superblock of ReiserFS has kind of signature (ReIsEr2FS). When I tried re-creation of superblock, the signature was written there. file -s on this partition also indicates "ReiserFR V3.6 now. But mount still considers it as ext3.
My impression is that during power down something got changed, but very locally, probably some offset. So that real reiser fs superblock is not where it should be (64K from the beginning of partition) and for that reason file system is not correctly recognized. Where is my old diskette with Norton Disk Editor :( ?
No, the structure of a reiserfs partition is radically different from an ext3 partition. There is no way that changing a few blocks can change one to the other: the entire disk has to be rewritten. There is no way a power failure or any glitch can do the conversion. Actually, there is no tool to convert partition type from ext3 to reiser or viceversa except an entire rewrite. A backup restore using dd, for example, would do it, if the backup was ext3. Some tools may thinkk it is reiserfs because they only look at the beginning of the partition. - -- Cheers / Saludos, Carlos E. R.
