Is XFS support broken?

[PSL]

I installed "Armbian 23.8.3 bookworm" to Odroid HC1. Installation was OK, it boots. Armbian is installed on microSDHC card. 

 

I wanted to format SATA drive with XFS but I cannot mount it.

 

1) I installed xfsprogs (apt install xfsprogs)

 

$ dpkg -la | grep xfs
ii  xfsprogs                          6.1.0-1                        armhf        Utilities for managing the XFS filesystem

 

2) I created GPT partition table on SATA drive and I created one partition, /dev/sdb1

 

# fdisk -l /dev/sdb
Disk /dev/sdb: 1.82 TiB, 2000398934016 bytes, 3907029168 sectors
Disk model: Generic         
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: EF0AF689-AAD7-C443-B5AE-03EFFC99E02D

Device     Start        End    Sectors  Size Type
/dev/sdb1   2048 3907028991 3907026944  1.8T Linux filesystem

3) I formated partition with xfs:

 

# mkfs.xfs /dev/sdb1

 

4) I checked partition with xfs_repair, no issues

# xfs_repair /dev/sdb1

 

5) Info about filesystem:

 

# xfs_info /dev/sdb1 
meta-data=/dev/sdb1              isize=512    agcount=4, agsize=122094592 blks
         =                       sectsz=4096  attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=0
         =                       reflink=1    bigtime=1 inobtcount=1 nrext64=0
data     =                       bsize=4096   blocks=488378368, imaxpct=5
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=238466, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

 

6) The issue, I cannot mount the partition:

 

# mount /dev/sdb1 /srv/
mount: /srv: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

 

# dmesg |grep XFS

Any idea what is broken? Is it kernel??

Maybe kernel is old, it is 5.4 in this build. Other builds of Armbian have kernel 6.1.53 (like OrangePi ZERO or NanoPI NEO)...

I tried to replicate this issue on i686 box running Debian Bookworm and it works there, no problem.

 

1) Create file for disk, 50GB

 

# dd  if=/dev/zero of=xfstest.bin bs=1M count=50000

 

2) Format disk with XFS

 

# mkfs.xfs xfstest.bin

 

3) show XFS details

 

# xfs_info xfstest.bin
meta-data=/dev/loop0             isize=512    agcount=4, agsize=3276800 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=0
         =                       reflink=1    bigtime=1 inobtcount=1 nrext64=0
data     =                       bsize=4096   blocks=13107200, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=16384, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

 

4) mount FS, no issue here!

 

# mount -o loop xfstest.bin /srv
#
# mount | grep xfs
/root/xfstest.bin on /srv type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)

 

5)  check dmesg

 

# dmesg | grep XFS
[2992759.600513] SGI XFS with ACLs, security attributes, realtime, quota, no debug enabled
[2992759.618175] XFS (loop0): Mounting V5 Filesystem
[2992759.649994] XFS (loop0): Ending clean mount

 

6) system info, kernel is 6.1.0

 

# uname -a
Linux worm 6.1.0-12-686-pae #1 SMP PREEMPT_DYNAMIC Debian 6.1.52-1 (2023-09-07) i686 GNU/Linux
#
# dpkg -l | grep xfsprogs
ii  xfsprogs                              6.1.0-1                        i386         Utilities for managing the XFS filesystem

 

So, I assume that issue is really the kernel 5.x that is delivered with Armbian for Odroid XU4 (HC1/HC2)...
