Hello again, Sorry about the quick follow up email. I realized that I alluded to the following in my initial email, but I realized that I forgot to directly address this issue. If the partition is resized when not currently mounted it seems to works fine. ``` root@debian11-vm-acoffin:~/tmp# gunzip ./foo.iso.gz root@debian11-vm-acoffin:~/tmp# resize2fs ./foo.iso resize2fs 1.46.2 (28-Feb-2021) Please run 'e2fsck -f ./foo.iso' first. root@debian11-vm-acoffin:~/tmp# e2fsck -f ./foo.iso e2fsck 1.46.2 (28-Feb-2021) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 3A: Optimizing directories Pass 4: Checking reference counts Pass 5: Checking group summary information ./foo.iso: ***** FILE SYSTEM WAS MODIFIED ***** ./foo.iso: 2321/7904 files (0.2% non-contiguous), 18945/32769 blocks root@debian11-vm-acoffin:~/tmp# resize2fs ./foo.iso resize2fs 1.46.2 (28-Feb-2021) Resizing the filesystem on ./foo.iso to 524288 (1k) blocks. The filesystem on ./foo.iso is now 524288 (1k) blocks long. ``` Regards, Alex Coffin
