What were you trying to do that didn't work?
Creating a filesystem with certain parameters, the parameters are taken from an existing filesystem, the goal is to reproduce the settings of the original filesystem. The original filesystem was originally created very small and then grown.
What is the impact of this issue to you?
It causes RHEL-56018. Customer is requesting RCA and Errata.
Please provide the package NVR for which the bug is seen:
xfsprogs-5.14.2-1.el9
How reproducible is this bug?:
well reproducible under specific conditions.
Steps to reproduce
Assuming an unused disk /dev/vdb available for tests:
- dnf -y install lvm2
- pvcreate -f /dev/vdb
- vgcreate vg /dev/vdb
- lvcreate --type thin-pool -l 95%FREE -n lvol1 vg
- lvcreate --type thin -V 90248839168b --thinpool lvol1 vg -n lv_log
- mkfs.xfs -f -i size=512 -d agcount=2869 -s size=512 -i attr=2 -i projid32bit=1 -m crc=1 -m finobt=1 -b size=4096 -i maxpct=25 -d sunit=128 -d swidth=128 -l version=2 -l sunit=128 -l lazy-count=1 -n size=4096 -n version=2 -r extsize=4096 /dev/mapper/vg-lv_log
- mkfs.xfs -f -i size=512 -d agsize=7680b -s size=512 -i attr=2 -i projid32bit=1 -m crc=1 -m finobt=1 -b size=4096 -i maxpct=25 -d sunit=128 -d swidth=128 -l version=2 -l sunit=128 -l lazy-count=1 -n size=4096 -n version=2 -r extsize=4096 /dev/mapper/vg-lv_log
Expected results
Filesystem is created.

If the size of the lv_log LV is varied a bit, one can get the error reported in https://bugzilla.redhat.com/show_bug.cgi?id=2211095 / RHEL-7960 instead.
With the LV size of -V 86128 one gets a variation of the error:
