the mkfs.<fs> linkx/tools are somewhat standartized so there _should_ be an mkfs.<fs> for every supported filesystem (doesn't mean debian has it :) > Note 2: script calls lsattr (part of e2fsprogs) which > means that versions prior to 1.37 will silently fail. ahem, why? rpm -qf /usr/bin/lsattr e2fsprogs-1.32-2mdk and that one works pretty fine too :) > I built e2fsprogs 1.38 to get past that one. > > Here is what I am seeing, all that I can tell is that > the attributes reported are different: > > Without the (-o attrs) option to mount command (for reiserfs, which absolutely _requires_ attrs to work with attributes :) > [mount /dev/loop0 /mnt] > > # showattr /mnt > ---bui- /mnt > ----ui- /mnt/file_9079 > ---bui- /mnt/dir_9079 yep, means the attributes were ignored, that's what reiserfs _wiithout_ attrs does ... > # ./lsattr /mnt/ > ./lsattr: Inappropriate ioctl for device While reading flags on /mnt/file_9079 > ./lsattr: Inappropriate ioctl for device While reading flags on /mnt/dir_9079 > (Which seems reasonable) yeah, no attributes no ioctl :) > Note 3: Some of the on-line documentation mentions an "xattrs" option to > reiserfs - my 3.6.14 only understands "attrs" (correct in the script). > > Next, umount and mount the test file with the "attrs" option > [mount -o attrs /dev/loop0 /mnt] > > Now we have (without any changes to the files) > > # showattr /mnt > ---bui- /mnt > ----UI- /mnt/file_9079 > ---Bui- /mnt/dir_9079 yes, attributes are now available ...
