index | next in thread | raw e-mail
I just tried to create a snapshot on my laptop and it paniced with the
following message:
panic: ffs_balloc: blk too big
-=-=-
vp = ap->a_vp;
ip = VTOI(vp);
fs = ip->i_fs;
lbn = lblkno(fs, ap->a_startoffset);
size = blkoff(fs, ap->a_startoffset) + ap->a_size;
if (size > fs->fs_bsize)
panic("ffs_balloc: blk too big"); <<<<<<<<
*ap->a_bpp = NULL;
if (lbn < 0)
return (EFBIG);
-=-=-
Trace within DDB is
panic
ffs_balloc
ffs_snapshot
ffs_mount
mount
syscall2
The filesystem is a 16k/2k FS.
