https://bugzilla.kernel.org/show_bug.cgi?id=194567 Bug ID: 194567 Summary: ext4 no longer mounts Product: File System Version: 2.5 Kernel Version: 4.4.48 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx Reporter: bugzilla.kernel.org@xxxxxxxx Regression: No I have a single ext4 filesystem on my workstatioon used to host mysql database files. I don't know how old it is (months, years), but I happen to keep the mkfs command used to create it (the device is 67108864 sectors): mke2fs -t ext4 -b 4096 -N 65536 -I 128 -L DB -m 0 -O dir_index,extent,filetype,flex_bg,^has_journal,large_file,^resize_inode,sparse_super,uninit_bg It worked fine till 4.4.47. it no longer mounts in 4.4.48: [ 206.596713] EXT4-fs (dm-24): VFS: Can't find ext4 filesystem [ 214.028205] EXT4-fs (dm-24): first meta block group too large: 2 (group descriptor block count 2) [ 242.185792] EXT4-fs (dm-24): first meta block group too large: 2 (group descriptor block count 2) e2fsck -f (from "e2fsck 1.43.4 (31-Jan-2017)") finds no errors. Not sure if this is a bug in mkfs, e2fsck, or the kernel, but since it is a regression in the kernel, I reported it here. -- You are receiving this mail because: You are watching the assignee of the bug.
