| Subject: [PATCH 5/5] rules: watch metadata changes in ide devices |
| |
| Formatting IDE storage does not trigger "change" uevents. As a result |
| clients using udev API don't get any updates afterwards and get outdated |
| information about the device. |
| ... |
| root@qemux86-64:~# mkfs.ext4 -F /dev/hda1 |
| Creating filesystem with 262144 4k blocks and 65536 inodes |
| Filesystem UUID: 98791eb2-2bf3-47ad-b4d8-4cf7e914eee2 |
| |
| root@qemux86-64:~# ls /dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2 |
| ls: cannot access '/dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2': No such file or directory |
| ... |
| Include hd* in a match for watch option assignment. |
| |
| Upstream-Status: Denied |
| |
| qemu by default emulates IDE and the linux-yocto kernel(s) use |
| CONFIG_IDE instead of the more modern libsata, so disks appear as |
| /dev/hd*. A similar patch rejected by upstream because CONFIG_IDE |
| is deprecated. |
