Environment
SUSE Linux Enterprise Server 15
SUSE Linux Enterprise Server 12
SUSE Linux Enterprise Server 12
Situation
While attempting to extend an existing logical volume to a size greater than 16 TiB and resize the ext3 filesystem on top of it, you may encounter the following error message: -
lvdisplay shows logical volume size as 17TB.
# resize2fs /dev/testvg/testlv
resize2fs 1.43.8 (1-Jan-2018)
resize2fs: New size too large to be expressed in 32 bits
lvdisplay shows logical volume size as 17TB.
# lvdisplay -m /dev/testvg/testlv

Resolution
Resize the filesystem to exactly 16 TiB (16777216 MB) which is the maximum size supported for the ext3 filesystem.
Else reduce the logical volume to exactly 16TB and resize the filesystem.
# resize2fs /dev/testvg/testlv 16777216M
resize2fs 1.43.8 (1-Jan-2018)
Filesystem at /dev/mapper/testvg-testlv is mounted on /mnt; online resizing required
old_desc_blocks = 896, new_desc_blocks = 1024
The filesystem on /dev/mapper/testvg-testlv is now 4294967295 (4k) blocks long.
ip-172-31-27-171:~ # df -h /mnt
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/testvg-testlv 16T 1.1M 16T 1% /mnt
Else reduce the logical volume to exactly 16TB and resize the filesystem.
Cause
The root cause of this issue is that the actual logical volume size is slightly higher than the maximum size supported for ext3 file systems in SUSE Linux Enterprise Server.
