Another problem with devfs is symlinks (eg: /dev/sda), the lvm dircache will contain only the long name (/dev/scsi/....). i have a couple of ideas, but no time to code (sorry) 1) using realpath in the tools to solve issue 2 2) checking if the devices mentioned in /proc/partition do really exist, else switch the cache to "scan the dev directory mode" but better than the above 3) add another structure to the cache which contains aliases to the device we have in the cache, aliases are added dynamically when found on the command line or in the VGDA of a PV. We use alias[c].name=possible alias; lstat(possible alias, &statbuf) if (S_ISLNK(statbuf.st_mode)) { alias[c].target=lvm_dir_cache_find(realpath(possible alias)); if !(alias[c].target) stat(realptah(possible alias), &statbuf) } if (S_ISBLK(statbuf.st_mode)) { alias[c].target=lvm_dir_cache_find_dev(statbuf.st_dev>>8,statbuf.st_mode&((1<<8)-1)); /* the above function has to be written*/ } if (!alias[c].target) complain(loudly); c++; then we modify lvm_dir_cache_find to loop also on alias[], before it starts searching th cache. regards, L.
