Public bug reported: 'man resize2fs' claims "If no units are specified, the units of the size parameter shall be the filesystem blocksize of the filesystem" but makes no mention of the units used in the minimum size report. The tool itself makes no mention of units.
Many users would assume the value was in bytes, or possibly KB. Despite the fact that the operating deals in file-system block-size units the output appears to be in units of 512-byte sectors. $ sudo dumpe2fs /dev/fujiVG/home | grep 'Block size' dumpe2fs 1.42 (29-Nov-2011) Block size: 4096 $ sudo resize2fs -P /dev/fujiVG/home resize2fs 1.42 (29-Nov-2011) Estimated minimum size of the filesystem: 5124061 $ df /home Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/fujiVG-home 30963708 2438852 26952120 9% /home $ df -B 4096 /home Filesystem 4K-blocks Used Available Use% Mounted on /dev/mapper/fujiVG-home 7740927 609713 6738030 9% /home $ df -B 512 /home Filesystem 512B-blocks Used Available Use% Mounted on /dev/mapper/fujiVG-home 61927416 4877704 53904240 9% /home ** Affects: e2fsprogs (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1494625 Title: 12:04: resize2fs: unclear/incorrect units in size report To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1494625/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
