config: ext4: increase x86 rootfs size for online resize #1669
Conversation
ext4 online resize on x86 rootfs fails unless the rootfs size is set to 2 GB or larger, this is very inconvenient because the only way to increase filesystem size is to do it with the filesystem unmounted. This is an example of the error when I try to resize it when mounted from my PC (this is the same error I get also in OpenWrt) ------- alby@openSUSE-xeon:/> sudo resize2fs /dev/sdd2 resize2fs 1.44.4 (18-Aug-2018) Filesystem at /dev/sdd2 is mounted on /run/media/alby/57f8f4bc-abf4-655f-bf67-946fc0f9f25b; on-line resizing required old_desc_blocks = 1, new_desc_blocks = 1 resize2fs: Invalid argument While checking for on-line resizing support ------- This commit restores commit dc6cc04 which was reverted later in commit 4cc1f1a imho (also reading the description) the revert was a mistake. "2 GB is overkill and was only added to allow unlimited ext4 resizing, which is a pretty rare use case. " That commit was not about allowing unlimited resizing. The issue here is that online resize does not work unless the filesystem size is 2GB or more, or maybe if we change the block size instead. Signed-off-by: Alberto Bursi <alberto.bursi@outlook.it>

Out of curiosity, why not just add another parition? |
You mean doing an extroot in a new partition? No it did not work when I tried. I could not even do it manually (i.e. mounting another partition over /overlay). Does it work for you? Still, even if it worked, I think it's stupid to require an extroot because you can't provide an expandable image. |

Unless you're using out of tree packages filling up 256Mbyte is quite a "challange"? :-) |

It seems like nobody is interested in merging this. I find 2GiB images just to be able to do online resizing quite excessive. I would just use squashfs+ext4. |

@ynezz The container needs more space, and I feel this partition is fine |

This commit restores commit dc6cc04
which was reverted later in commit 4cc1f1a
imho (also reading the description) the revert was a mistake.
"2 GB is overkill and was only added to allow unlimited ext4 resizing,
which is a pretty rare use case. "
That commit was not about allowing unlimited resizing.
The issue here is that online resize does not work
unless the filesystem size is 2GB or more,
or maybe if we change the block size instead.
