Subject: Re: PROBLEM: ext4 resize2fs on-line resizing panic

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@...ian11-vm-acoffin:~/tmp# gunzip ./foo.iso.gz
root@...ian11-vm-acoffin:~/tmp# resize2fs ./foo.iso
resize2fs 1.46.2 (28-Feb-2021)
Please run 'e2fsck -f ./foo.iso' first.

root@...ian11-vm-acoffin:~/tmp# e2fsck -f ./foo.iso
e2fsck 1.46.2 (28-Feb-2021)

./foo.iso: ***** FILE SYSTEM WAS MODIFIED *****

root@...ian11-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.
```
