[plug] JFS pros, cons?

[Denis Brown]

Dear PLUG gurus,

I'm going through the motions of setting up what I hope will be a high 
availability Linux machine.   It will have a UPS, dual SCSI disks in RAID-1 
and tape backups will be made daily (and tested!)   And so it comes to the 
question of which file system to choose...

For example, is anyone using JFS and have comments to make regarding 
it?   I'm not so much fussed about data loss caused by user errors -- the 
data will be backed up daily in any case so not a lot of value is likely to 
be lost to that mechanism.   What I am concerned about is data integrity 
issues that are system related.   Is JFS sufficiently mature in its open 
form?  The commercial package seems to have been running fine on AIX for 
many years and I'm sure that IBM's customers would jump up and down if 
there were problems :-)

In PLUGgers' experience, is Reiser the way to go?   XFS?   Something 
else?   Given that I have RAID-1 and a UPS, would ext2 be good 
enough?   After all, I haven't had any problems with it over the years.

My aim is to have the system boot from the RAID array and have the swap 
partition in the RAID as well.   Do any of the file systems prevent either 
of these happening?  In other words is it better to have swap as ext2, for 
example, the boot as Reiser and the root (and everything else) as JFS?

Your thoughts would be appreciated.
Denis
