What were you trying to do that didn't work?
The file utility doesn't print correctly the filesystem UUID of an erofs image on x86_64, aarch64 and ppc64le. An example from x86_64:
[root@kvm-03-guest16 ~]# mkdir test [root@kvm-03-guest16 ~]# mkfs.erofs test_x86_64.img test mkfs.erofs 1.8.4 Build completed. ------ Filesystem UUID: 6445a18d-62a5-4a06-ad2a-dafddcce2886 Filesystem total blocks: 1 (of 4096-byte blocks) Filesystem total inodes: 1 Filesystem total metadata blocks: 1 Filesystem total deduplicated bytes (of source files): 0 [root@kvm-03-guest16 ~]# [root@kvm-03-guest16 ~]# blkid test_x86_64.img test_x86_64.img: UUID="6445a18d-62a5-4a06-ad2a-dafddcce2886" BLOCK_SIZE="4096" TYPE="erofs" [root@kvm-03-guest16 ~]# [root@kvm-03-guest16 ~]# file test_x86_64.img test_x86_64.img: EROFS filesystem, compat: SB_CHKSUM MTIME, blocksize=12, exslots=0, uuid=8DA14564-A562-064A-AD2A-DAFDDCCE2886 [root@kvm-03-guest16 ~]#
On s390x (big endian), the UUID is printed correctly:
[root@s390x-kvm-106 ~]# mkdir test [root@s390x-kvm-106 ~]# mkfs.erofs test_s390x.img test mkfs.erofs 1.8.4 Build completed. ------ Filesystem UUID: 9fdd10bb-33fc-48c7-9f93-f9258c881b70 Filesystem total blocks: 1 (of 4096-byte blocks) Filesystem total inodes: 1 Filesystem total metadata blocks: 1 Filesystem total deduplicated bytes (of source files): 0 [root@s390x-kvm-106 ~]# blkid test_s390x.img test_s390x.img: UUID="9fdd10bb-33fc-48c7-9f93-f9258c881b70" BLOCK_SIZE="4096" TYPE="erofs" [root@s390x-kvm-106 ~]# file test_s390x.img test_s390x.img: EROFS filesystem, compat: SB_CHKSUM MTIME, blocksize=12, exslots=0, uuid=9FDD10BB-33FC-48C7-9F93-F9258C881B70 [root@s390x-kvm-106 ~]#
Please provide the package NVR for which the bug is seen:
erofs-utils-1.8.4-2.el10
util-linux-core-2.40.2-5.el10
file-5.45-7.el10
How reproducible is this bug?:
Always on little endian architectures.
Steps to reproduce
- mkdir test
- mkfs.erofs test_x86_64.img test
- file test_x86_64.img
Expected results
Incorrect UUID printed - parts of the UUID are swapped.
Actual results
UUID printed correctly.
