Comment #9 on issue 1064 by [email protected]: Cannot install VM on
Gluster bankend storage
https://code.google.com/p/ganeti/issues/detail?id=1064
I have found the problem is caused by function `format_disk0` in create
script.
root@node1:/srv/ganeti/os/debootstrap# cat create
[...]
45
46 DEVICE_SIZE=$(blockdev --getsize64 $blockdev)
47 if [ "$DEVICE_SIZE" -lt $MIN_DEV_SIZE ]; then
48 echo "Device size is too small ($((DEVICE_SIZE/1048576)) MB)" 1>&2
49 echo "Required size is at least 256MB" 1>&2
50 exit 1
51 fi
52
53 echo "999 DEVICE_SIZE is $DEVICE_SIZE"
54
55 if [ "$PARTITION_STYLE" = "none" ]; then
56 echo "999 style none"
57 filesystem_dev=$blockdev
58 echo "999 filesystem_dev is $blockdev"
59 elif [ "$PARTITION_STYLE" = "msdos" ]; then
60 echo "999 style msdos" <---------------------------
61 # Create one big partition, and make it bootable
62 format_disk0 $blockdev
63 echo "999 call <---------------------------
format_disk0"
64 filesystem_dev=$(map_disk0 $blockdev)
65 echo "999 filesystem_dev is $blockdev"
66 CLEANUP+=("unmap_disk0 $blockdev")
67 else
68 echo "Unknown partition style $PARTITION_STYLE" 1>&2
69 exit 1
70 fi
71
72 mke2fs -Fjqt $OSP_FILESYSTEM $filesystem_dev
73 root_uuid=$($VOL_ID $filesystem_dev )

The related codes in create is "format_disk0 $blockdev ". $blockdev
is "/dev/loop2". It seems that something wrong with "/dev/loop2". $blockdev
is passed into format_disk0 to execute as the command "sfdisk -H 64 -S 32
-u S --quiet --Linux $blockdev". When I run this command as follows, it
shows me the same error.
root@node1:/var/log/ganeti/os# sfdisk -H 64 -S 32 -u S --quiet --Linux
/dev/loop2

^C
I am trying to fix this problem.
