Subject: [linux-lvm] The size specified by "lvcreate -L" is not accurate
Date: Thu, 2 Sep 2021 03:26:42 +0000 [thread overview]
Message-ID: <PH0PR11MB501412E2C1081FA98208E545F1CE9@PH0PR11MB5014.namprd11.prod.outlook.com> (raw)

Per https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/tree/doc/RelNotes/v1.46.4.txt, after e2fsprogs upgrades to 1.46.4, the defaults for mke2fs now call for 256 byte inodes for all file systems (with the exception of file systems for the GNU Hurd, which only supports 128 byte inodes) and use "lvcreate -L 50 -n lv_test1 vg_test && mke2fs /dev/vg_test/lv_test1" and then continue to check the partiontion as below.(use lvm2 2.03.11 for the test)
# df -h | grep dev/mapper/vg_test-lv_test1
/dev/mapper/vg_test-lv_test1 48M 14K 46M 1% /mnt/lv-test
Though claim 50M as above, but it turns out to be only 48M.
Thanks,
