In order for me to reproduce the problem, I had to get access to the partition before mounting it. It seems as if (a) the file gets written to extents on the disk, and (b) that the inode is written to the log, but the log is never flushed such that the metadata never make it to the filesystem. Mounting the filesystem on next reboot causes the log to be replayed and consistency to be restored. I assume xfs_db does the same. Grub, on the other hand, tries to get the file, but it does not exist in the directory (and grub cannot replay the log), so it fails to find it. -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck invalid/expired pgp subkeys? use subkeys.pgp.net as keyserver! spamtraps: madduck.bogus@xxxxxxxxxxx "doesn't he know who i think i am?" -- phil collins
