-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package: e2fsprogs Version: 1.44.4-2
The mount options set in "e2fsprogs" are not being used by the OS, regardless whether there are corresponding entries in "/etc/fstab". Here is my example: ===BEGIN OUTPUT=== root@AVENTHEIM:/u/h/root>tune2fs -l /dev/sda tune2fs 1.44.4 (18-Aug-2018) Filesystem volume name: DEBIAN Last mounted on: /root Filesystem UUID: c5971091-77d2-40fe-9095-54bb0ff96a2c Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr dir_index sparse_super2 needs_recovery extent flex_bg inline_data large_file uninit_bg Filesystem flags: signed_directory_hash Default mount options: discard Filesystem state: clean Errors behavior: Remount read-only Filesystem OS type: Linux Inode count: 228960 Block count: 117220824 Reserved block count: 0 Free blocks: 107372244 Free inodes: 130667 First block: 1 Block size: 1024 Fragment size: 1024 Blocks per group: 8192 Fragments per group: 8192 Inodes per group: 16 Inode blocks per group: 4 Flex block group size: 16 Filesystem created: Wed Oct 17 19:58:28 2018 Last mount time: Tue Oct 30 08:04:00 2018 Last write time: Tue Oct 30 08:04:00 2018 Mount count: 3 Maximum mount count: -1 Last checked: Mon Oct 29 08:13:17 2018 Check interval: 0 (<none>) Lifetime writes: 267 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 32 Desired extra isize: 32 Journal inode: 8 First orphan inode: 163356 Default directory hash: legacy Directory Hash Seed: a4bd0a95-469a-48ff-8d9e-c1a3e4674ec8 Journal backup: inode blocks root@AVENTHEIM:/u/h/root>mount |grep /dev/sda /dev/sda on / type ext4 (rw,relatime,lazytime) root@AVENTHEIM:/u/h/root>cat /etc/fstab /dev/block/8:0 / ext4 lazytime 0 1 ===END OUTPUT=== Note that "discard" is not in the mount parameters despite that I have set it in "tune2fs". (It is an SSD and it supports TRIM. And yes, I do not partition it.) Another example: ===BEGIN OUTPUT=== root@AVENTHEIM:/u/h/root>tune2fs -l /dev/sdc tune2fs 1.44.4 (18-Aug-2018) Filesystem volume name: USERDATA Last mounted on: /run/mount/sdc Filesystem UUID: afb8ef7a-29bc-42fa-8d6b-970f5d91f45a Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal dir_index sparse_super2 needs_recovery extent flex_bg large_file uninit_bg Filesystem flags: signed_directory_hash Default mount options: bsdgroups uid16 Filesystem state: clean Errors behavior: Remount read-only Filesystem OS type: Linux Inode count: 1907744 Block count: 1953506646 Reserved block count: 0 Free blocks: 1768323885 Free inodes: 1905162 First block: 0 Block size: 4096 Fragment size: 4096 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 32 Inode blocks per group: 1 Flex block group size: 16 Filesystem created: Wed Oct 17 21:07:45 2018 Last mount time: Tue Oct 30 08:04:37 2018 Last write time: Tue Oct 30 08:04:37 2018 Mount count: 3 Maximum mount count: -1 Last checked: Mon Oct 29 08:13:35 2018 Check interval: 0 (<none>) Lifetime writes: 1551 GB Reserved blocks uid: 65534 (user nobody) Reserved blocks gid: 65534 (group nogroup) First inode: 11 Inode size: 128 Journal inode: 8 Default directory hash: legacy Directory Hash Seed: b99b9c29-ee43-423e-b4bd-0321c1f7d12a Journal backup: inode blocks root@AVENTHEIM:/u/h/root>mount |grep /dev/sdc /dev/sdc on /run/mount/sdc type ext4 (rw,nosuid,nodev,relatime,resuid=65534,resgid=65534,user) ===END OUTPUT=== Again, the default options are not being honoured. I mounted it using "pmount -e" but it should not affect options like "bsdgroups" and "uid16". Also, it is not in "/etc/fstab". -- Please reply to this e-mail with UTF8-encoded plain text.
