afs_UFSGetVolSlot does
        tfile = osi_UFSOpen(volumeInode);
        code = afs_osi_Write(tfile, sizeof(struct fvolume) * afs_FVIndex,
                         &staticFVolume, sizeof(struct fvolume));
        if (code != sizeof(struct fvolume))
            osi_Panic("write volumeinfo");
        osi_UFSClose(tfile);

and it lost because afs_osi_Write didn't return sizeof(struct fvolume)

perchance was your disk full? because one thing which will cause this is:
        if (code == ENOSPC) afs_warnuser("\n\n\n*** Cache partition is
FULL - Decrease cachesize!!! ***\n\n");
        code = -1;
