I've been booting from xfs with lilo, and more recently, 'grub', from suse 7.x up to 11.1. I haven't any recent probs concerning lilo, but I saw this same type of issue and a solution in Ubuntu's bug database (though they encountered this problem 3 years ago and automatically used a workaround to not corrupt a user's choice of filesystem. The issue was Grub not being able to write to the root directory if it is formatted as an XFS partition. The response was Ubuntu's workaround (maybe openSuSE could figure out how they did this...it is open source...and they could adopt their solution rather than just throwing up their hands and saying they don't support XFS). The Ubuntu installer automatically uses lilo in the case where the root (or boot) file system is XFS. Thus no ever sees the problem grub has with XFS, they simply use the more primitive, but more reliable 'lilo' bootloader. It's a bit weird to see some people at SuSE prefer to work around a bootloader bug by disallowing user-desired file systems, rather than by simply using a bootloader that doesn't have the bug. I would have thought that most people would have simply chosen to Not use a buggy boot-loader and use a more reliable alternative, over disallowing file-systems that are unsupported by the buggy-boot loader. Some folks at Suse must have a real 'thing' for 'grub' to rate it's importance more highly than users' file system choices... But I would really suggest that OpenSuse follow Ubuntu's example -- just use a bootloader that works. Don't limit file-system selection based on the bugs of a bootloader (same would be true if lilo didn't work with some filesystem and grub did...use the combinations that work -- to rigidly disallow anything that grub suggests someone needs to re-examine their priorities. FWIW, though, I _am_ using grub, with XFS...but if grub broke, I'd switch back to lilo in a heartbeat, NOT reformat my boot or root partition to accommodate the bootloader's bugs de jour. -linda _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 10+ messages in thread

(!)... The report below says that grub can't WRITE to XFS. Supposedly the 'default'-file. Don't know what else GRUB may want to write. Which, depending on preference, is superfluous anyway. So if you switch that off (don't know how, never used it myself) all should be fine. OTOH as long as you can live with a separate boot-partition, what's the problem of formating it with ext2. fsck-times for a single/double-digit MB boot-partition are negligible. I've been using XFS for anything but boot-partitions for years. IMHO GRUB is more important than free choice of boot-partition filesystem.

I've always been using a small seperate ext2 Partition for /boot, since i've found this to be the most robust solution. Also when other Filesystems like reiser4 or btrfs come in play. I'd say XFS support in Grub is nice to have, but not a must. Maybe the distributions should just default to an ext2 Partition for /boot. That would keep most people happy, wouldn't it? just my 2c _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 10+ messages in thread

I would much prefer to have that support, since I tend to partition my disks as one single XFS partition, which can be backed up with xfsdump easily. If anyone has run tests with Grub2 in its current state of development, I would be interested in the results. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 10+ messages in thread

Well, I see we have a thread... Grub makes bad assumptions about what it can do to a filesystem, and the problems lie with reading directly from and writing directly to a filesystem's block device while it's -mounted-, when grub is being installed. Sometimes this even trips up ext3 as well, but the problem is more obvious with xfs. If you look at all the sync sync sync sleeps in grub you'll see that they are desperately trying to make the block device coherent with the filesystem, which they simply cannot do with syncs and sleeps. Some distros have tried adding xfs_freeze calls to quiesce the filesystem, and when this can be done, it generally works, but it'd be better if grub would just not do IO to the device while it's mounted, in general. That being said, hch's recent xfs sync changes should make this much more likely to succeed in the future at least, despite grub's notions of what's safe. -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 10+ messages in thread
