Is there any way to clean up stale devices/symlinks in the /dev/disk/by-id folder?
I have a SLES 11.1 with a SAN connected disk array. I'm using a program for disk replication and presenting the disks to the server. The program also enables the disks and creates a volume group on top. When it finishes it cleans up after itself (remove vg, unpresent etc.). After a few days of running it, the /dev/disk/by-id folder holds a large number of files (mostly softlinks to lvm devices). Is there any way to clean/remove these? So far only reboot helps  |

Do you mean that the directory is full of links that point nowhere? If so, this command will remove them.
| Code: | | find -L /dev/disk/by-id -type l -exec rm "{}" + |
The -L options makes find follow symbolic links and use information fro the file linked to rather than the link itself, so the only links it sees as links (-type l) are broken ones (or links that point to an unreadable file, but that won't happen if you run this as root).

Thank you nelz, that does clean up the stale links.
I'd rather use a udev cleanup command or something similar though, since udev creates these links and takes care of them if I'm not mistaken. Is there any udev (or something similar) cleanup mode/command to take care of this? So far I haven't found any clues on "proper" removal of these stale softlinks.
Thanks for the help |

| I'm surprised you had stale links, because AFAIU, udev creates/deletes these dynamically (via kernel uevents) as any disks are detected or removed, but maybe your disk replication app is responsible for this behaviour? |
