Thank you Leslie for your patch.
However it's not enough for my needs because the type of filesystem is still
checked so parted refuses to enlarge the partition marked xfs.
So I patched a little more so it doesn't check the filesystem type.
Here is my patch:
http://opensource.synerway.com/patchs/parted-1.7.0rc4-nofs_resize.patch
It seemd to work well until today.
I created a new partition /dev/hda4 lie it :
$ parted /dev/hda mkpart 25000 32000
I create an xfs on it:
$ mkfs.xfs /dev/hda4
Then I enlared it:
$ parted /dev/hda resize 4 25000 38000
And I got:
$ cat /proc/partitions
...
3 4 12695312 /dev/hda4
Then I mounted it and performed a successfull xfs_growfs on it.
Then it appeared to not work anymore.
Here's what I did:
$ parted /dev/hda rm 4
$ parted /dev/hda print
...
3 3000MB 25GB 22GB xfs
$ parted /dev/hda resize 3 3000 38000
$ parted /dev/hda print
...
3 3000MB 38GB 35GB xfs
$ cat /proc/partitions
...
3 3 21484375 /dev/hda4
The content in /proc/partitions indicates that the growth of the partition has
not been taken into account by the system or the kernel.
Then mounting it and performing an xfs_growfs fails because it considers the
partition is still 22GB large and there is no space left to enlarge the xfs
filesystem.
It seems that parted does a part of the work wrong, probably because of my
patch because I backported my patch for the 1.6.23 version of parted and it
behaves the same.
It would be helpfull it you could have a look at my patch and tell me what's
wrong if you can.
If you reply to this message, please make a group reply because I won't be here
next week and my collegue that I put in cc can take the info.
Thank you a lot.
Pascal
