Then again, better > speed never hurts. we use solaris ufs on our current fileservers, but xfs practically everywhere else. this is mostly due to our irix heritage but xfs has some benefits that ext3 does not have (like extents). xfs is certainly quite a bit more mature than ext3 in my opinion. ext4 is an attempt to get some of these xfs features into ext3. as far as bugs with xfs -- not too many. we have done some really bad things to the xfs filesystems as well (like power failures several times in one week). yes, i think extents probably arent a huge win for afs fileservers as they currently exist. it isnt clear to me that zfs is a big win for afs either. you need more storage? add another vicep. dont expand your existing volumes. yes, you might need to do a little more volume management but errors in a single filesystem wont potentially get all your data. _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
