Problem between XFS and JFS

[Ivan Kocher <ikocher@xxxxxxxxxxxxxx>]

Hi,

Yesterday I was hit by a nasty bug ...

I tried to change the filesystem of a couple machines from XFS to JFS, 
so compiled kernel 2.4.23 with XFS (patch) and JFS.  Once the jfs root 
partition was up, it booted, and xfs "tried" to repair the partition.  I 
 booted using my default setup and later after remaking all again using 
init=/bin/bash rw, and even later init=/bin/bash ro

In the first two cases cases, xfs tried its "repair", teling that it 
recovered the journal... :( trashing the fs.

When I booted in the third case, (ro) no problem...

I wonder ... does xfs has some check for some magic in there?  I tried 
in all machines, and in all it damaged the mounted / jfs fs ...


Any ideas?


Also, will there ever be a xfs patch for 2.4.24??  I know 2.4.25 has 
it... but for some reason I am having problems with a qlogic 2312 board 
with 2.4.25 ... :( so I was thinking on testing 2.4.24 ... ???



Thanks,

Ivan

PS: i'm still wondering why I did what i did... still don't see the real 
need ...
