Package: util-linux
Version: 2.20.1-5.3
Severity: normal
Dear Maintainer,
Blockdev --report fails on non-harddisk devices (NBD, loop, ...):
nasc0:root ~ 277 # blockdev --report /dev/nbd0 /dev/loop0
RO RA SSZ BSZ StartSec Size Device
blockdev: ioctl error on /dev/nbd0
blockdev: ioctl error on /dev/loop0
The problem appears to be that blockdev attempts to obtain
the device's geometry, which does not apply to such devices:
From disk-utils/blockdev.c:
[snip]
if (ioctl(fd, BLKROGET, &ro) == 0 &&
ioctl(fd, BLKRAGET, &ra) == 0 &&
ioctl(fd, BLKSSZGET, &ssz) == 0 &&
ioctl(fd, BLKBSZGET, &bsz) == 0 &&
----> ioctl(fd, HDIO_GETGEO, &g) == 0 &&
blkdev_get_size(fd, &bytes) == 0) {
printf("%s %5ld %5d %5d %10ld %15lld %s\n",
ro ? "ro" : "rw", ra, ssz, bsz, g.start, bytes, device);
[snip]
Kind regards,
Rogier.
