julian 96/11/12 17:45:58 Modified: sys/ufs/ffs ffs_vfsops.c Log: Submitted by: Archie and me. We encountered an interesting situation where the superblock for a file system got written to disk with the "fs_fmod" flag set to one. It appears that this flag is normally supposed to be cleared during ffs_sync(), but we experienced a crash, or some other weird occurrence that left it on the disk set to 1. Later this partition was mounted read-only... and the fs_fmod field was never cleared, causing ffs_sync() to panic "rofs mod" when trying to unmount that filesystem (ffs_vfsops.c: line 790). fix: set this bit to 0 when you load the superblock from disk. (see more complete mail on this to hackers) Revision Changes Path 1.42 +3 -1 src/sys/ufs/ffs/ffs_vfsops.c
