Package: grub2 Version: 2.12~rc1-9 Severity: Serious control: forwarded -1 https://savannah.gnu.org/bugs/?64376
I have a single XFS partition which contains the root filesystem and the boot partition. Since the recent upgrade to the 2.12 series I can't boot anymore because grub complains that it can't find normal.mod and remains in the rescue shell. The ls command kind of works. A ls in /boot/grub/i386-pc/ (where the normal.mod should be) shows a few files and then abort with the error message: 'error: invalid XFS directory entry'. I figured out that if I remove that directory and create a new one only with normal.mod then it was able to find it and complained about onother file. I then repeated the game until I had more files… The invocation of grub-install copied all files and broke it again. I then looked at various places and stumbled uppon https://savannah.gnu.org/bugs/?64376 and this indeed matches what I see. I rebuilt the grub2 package with commit ef7850c757fb3 ("fs/xfs: Fix issues found while fuzzing the XFS filesystem") reverted, installed from a rescue system and voila it boots again. My xfs filesystem is a normal v5 as in: | # xfs_info /dev/sdb1 | meta-data=/dev/sdb1 isize=512 agcount=4, agsize=655360 blks | = sectsz=512 attr=2, projid32bit=1 | = crc=1 finobt=1, sparse=1, rmapbt=1 | = reflink=1 bigtime=0 inobtcount=0 nrext64=0 | data = bsize=4096 blocks=2621440, imaxpct=25 | = sunit=0 swidth=0 blks | naming =version 2 bsize=4096 ascii-ci=0, ftype=1 | log =internal log bsize=4096 blocks=3693, version=2 | = sectsz=512 sunit=0 blks, lazy-count=1 | realtime =none extsz=4096 blocks=0, rtextents=0 Sebastian
