https://bugzilla.kernel.org/show_bug.cgi?id=217965 --- Comment #4 from Ivan Ivanich (iivanich@xxxxxxxxx) --- (In reply to Theodore Tso from comment #3) > What sort of information can you give about the ext4 file system where this > is happening? How much free space is there? Can you run "df" and > "dumpe2fs -h" on the system so we can see which file system features were > enabled? Also, can you specify the kind of the block device? > > Differential debugging would be useful. For example, can you try is to copy > the file system image to a hardware, and see if you can reproduce the > behavior using the same kernel build workload? What if you copy to the > file system image to a USB attached SSD, and see if you can reproduce the > behavior? What you attach the USB attached SSD, and use a freshly > formatted ext4 file system? Does it reproduce then? If the file system > is nearly full, what if you delete a lot of unused space, to provide a lot > more free space, and see if it reproduces then? mount |grep sdb2 /dev/sdb2 on /mnt/sdb2 type ext4 (rw,relatime,stripe=32752) df /mnt/sdb2/ Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb2 2667140496 2125391752 539022500 80% /mnt/sdb2 dumpe2fs -h /dev/sdb2 dumpe2fs 1.47.0 (5-Feb-2023) Filesystem volume name: <none> Last mounted on: /mnt/sdb2 Filesystem UUID: 3bd82ee7-f08a-4a23-8e50-2df3786b0858 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: user_xattr acl Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 169369600 Block count: 677467392 Reserved block count: 677465 Overhead clusters: 10682268 Free blocks: 135437186 Free inodes: 168057645 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 862 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 RAID stride: 32752 Flex block group size: 16 Filesystem created: Wed Jun 25 13:10:17 2014 Last mount time: Mon Oct 2 18:46:12 2023 Last write time: Mon Oct 2 18:46:12 2023 Mount count: 23 Maximum mount count: -1 Last checked: Thu Sep 28 14:37:21 2023 Check interval: 0 (<none>) Lifetime writes: 84 TB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: a90aaa2d-577c-4181-83f9-696dee7ea92d Journal backup: inode blocks Journal features: journal_incompat_revoke Total journal size: 128M Total journal blocks: 32768 Max transaction length: 32768 Fast commit length: 0 Journal sequence: 0x002a8661 Journal start: 9556 I don't have physical access to this machine so can't do any manipulations to the hardware or attaching USB drives etc. Device is Model Family: Toshiba 3.5" DT01ACA...
