Hi,

I have a fileserver which mounted a 4TB rbd, which is ext4 formatted.

I grow that rbd and ext4 starting with an 2TB rbd that way:

rbd resize testpool/disk01--size 4194304

resize2fs /dev/rbd0

Today I wanted to extend that ext4 to 8 TB and did:

rbd resize testpool/disk01--size 8388608

resize2fs /dev/rbd0

=> which gives an error: The filesystem is already 1073741824 blocks. Nothing to do.


       I bet I missed something very simple. Any hint? Thanks and regards . Götz

Try "partprobe" to read device metrics again.

Did not change anything and did not give any output/log messages.
