Eric Sandeen 149041070d ext4: lighten up resize transaction requirements ... When resizing online, setup_new_group_blocks attempts to reserve a potentially very large transaction, depending on the current filesystem geometry. For some journal sizes, there may not be enough room for this transaction, and the online resize will fail. The patch below resizes & restarts the transaction as necessary while setting up the new group, and should work with even the smallest journal. Tested with something like: [root@newbox ~]# dd if=/dev/zero of=fsfile bs=1024 count=32768 [root@newbox ~]# mkfs.ext3 -b 1024 fsfile 16384 [root@newbox ~]# mount -o loop fsfile mnt/ [root@newbox ~]# resize2fs /dev/loop0 resize2fs 1.40.2 (12-Jul-2007) Filesystem at /dev/loop0 is mounted on /root/mnt; on-line resizing required old desc_blocks = 1, new_desc_blocks = 1 Performing an on-line resize of /dev/loop0 to 32768 (1k) blocks. resize2fs: No space left on device While trying to add group #2 [root@newbox ~]# dmesg | tail -n 1 JBD: resize2fs wants too many credits (258 > 256) [root@newbox ~]# With the below change, it works.
