Subject: writable packet CD mounting in 2.6.26.x?
Date: Wed, 06 Aug 2008 20:12:49 +0100 [thread overview]
Message-ID: <87ej52vtxq.fsf@hades.wkstn.nix> (raw)
It seems to be impossible to mount packet-written CD-RWs writably in
2.6.26.x, even as root. Things worked in 2.6.25.x.
hades:/tmp# ls -l /dev/pktcdvd
total 0
brw-rw-rw- 1 root root 254, 0 2008-08-05 00:45 cdrw
crw-r--r-- 1 root root 10, 63 2008-08-05 00:44 control
brw-rw-rw- 1 root cdrom 254, 0 2008-08-05 00:45 pktcdvd0
hades:/tmp# mount -o rw /dev/pktcdvd/cdrw /mnt/pcdrw
mount: block device /dev/pktcdvd/cdrw is write-protected, mounting read-only
hades:/tmp# mount -o rw /dev/pktcdvd/pktcdvd0 /mnt/pcdrw
mount: block device /dev/pktcdvd/pktcdvd0 is write-protected, mounting read-only
The strace says that we get -EROFS always, now:
mount("/dev/pktcdvd/cdrw", "/mnt/pcdrw", "udf"..., MS_NOSUID|MS_NODEV|MS_NOEXEC|0x200000, NULL) = -1 EROFS (Read-only file system)
Anyone got any ideas? There are no suspicious-looking changes in
pktcdvd.c itself, so maybe this lies deeper in the block layer. Or
perhaps I'm mounting it wrong in some obscure way.
