For me Partitions are partitions and filesystems are filesystems. I can have a partition with a filesystem formatted as ext3, but it is evrytime a partition. So you can treat it as a partition. > > So to resize a partition you can use all tools related to it (for > > examples fdisk) > > fdisk does not resize partitions, unless you delete it and recreate it, but > then you loose all data.

However, for some reason, the resize option is disabled in both. fdisk permit you to manage partitions, but never you loose data, if you know what you are doing. I'm working with partitions every days, and I never loose data. > > To resize the filesystem you have to use other command. > > ext2resize I don't remember but I think works online. As mentioned in other post, I suggest reading the LVM-Howto. But to summarize the steps. If you want to extend a filesystem by extend also the partition you have to: 1. copy your partition configuration by for example the 'fdisk -l' command. There are other command that permit to have a simple file that can be used to reconfigure the partition table, but I don't remember which because I'm not using it. 2. Calculate the dimension of your new partition, standing that the first block as to be the same as before (otherwise you can't see data). Note that you can't see data, but data is not lost. If you reconfigure the partition as before, you can see the same data. 3. Maybe you need to reboot before you can use the new disk layout. 4. try to use the filesystem by mount it. 4.1 Note that df let you see the old dimension of the filesystem, because filesystem is not partition (even if the partition size is increased). 5 Extend your filesystem as you want. 6. After extending filesystem whit resize2fs you must check filesystems If you want to shrink fileystem I suggest other steps, even if is possible in some case to be done online. 1. Stop user accessing data 2. Umount filesystem 3. resize filesystem (shrink) 3.1 a test is made to be sure that the new dimension is possible without data loss. 3.2 check filesystem and remount it (if you want to be sure that filesystem is there) 4. calculate the new partition dimension in block, and change it. be carefull in the calc 5. Maybe you need to reboot before you can use the new disk layout. 6. Try to use the filesystem by mount it or check only without doing nothing to filesystem. If you trouble reconfiguring partitions, and try to check filesystem with repair mode, you can loose data. 7. if it's ok, resize the filesystem. This is because you can leave some MB or GB without knowning it. Bye Ambrogio -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
