#Extend ext4 partition windows

I thought that I could have a copy of any file on my windows partition, so I wouldn't need it on the Ubuntu one. I had allocated 10GB to Ubuntu during the installation a year and a bit ago. (GParted is confused, the total of all partitions is 426GB, but the manufacturer's sticker clearly says '320GB HDD'.) StackExchange.System specs: Acer Aspire 5738Z, Ubuntu 11.10 with GParted. InitTagRenderer(''.split(' '), ''.split(' '), channelOptions) Mke2fs: Size of device (0x123456789 blocks) is too big to be expressed in 32 bits using a blocksize of 4096. It was only necessary to initiate the upgrade.ДЇor reference, there is a similar error message mke2fs will print if it is asked to create a huge device with inappropriate options: You will not need any non-Ubuntu version of e2fsprogs for continued operation of the upgraded filesystem - the kernel supports those for quite some time now. If errors occur, do not panic and do not attempt to write to the volume consult someone with extensive knowledge of the filesystem, as further operations would likely destroy data! This is not an indication of any serious issue and you may chose to fix it now or later. The -p flag enabled progress bars - but those only display after some initial steps.Д®2fsck of newer versions may suggest to fix timestamps or extent trees that previous versions handled badly. If you do not pass a size on the command line, resize2fs assumes 'grow to all space available' - this is typically exactly what you want. $ sudo resize2fs -p /dev/mapper/target-device On a typical HDD RAID, this takes 4 minutes of high IO & CPU load. $ sudo resize2fs -b /dev/mapper/target-device Step 3: Enable 64bit support in the filesystemД¬onsult man tune2fs and man resize2fs - you may with to change some filesystem flags. $ sudo e2fsck -fn /dev/mapper/target-device # use `./resize2fs` instead of `resize2fs` for the rest of the steps # if this prints any lower version, panic $ git clone -b v1.44.2 e2fsprogs & cd e2fsprogs # if this prints version 1.43 or above, continue to step 1

If you are on 16.04 and cannot upgrade to a newer Ubuntu release, you will have to enable source package support and install a newer version manually: Ubuntu 18.04 () ships with e2fsprogs 1.44.x (good!) Ubuntu 16.04 () was released with e2fsprogs 1.42.12 ()Д®2fsprogs 1.43 () is the 1st release capable of upgrading extfs address size.

Make sure (check uname -r) you are running a kernel that can properly handle 64bit ext4 filesystems - you want to use a 4.4.x kernel or later (default Ubuntu 16 and above).ДЄcquire e2fsprogs of at least version 1.43.

Check $ cat /proc/partitions and reboot if necessary.

After changing hardware RAID configuration, linux may or may not immediately acknowledge the new maximum size.

First resize & verify all surrounding volumes (partition tables, encryption, lvm).

You must have your valuables stored elsewhere as well. Regular disk errors will cause harm otherwise.

This size of volume must be backed by RAID.

#Extend ext4 partition 64 Bit

It is possible to upgrade your ext filesystem to 64 bit addresses, allowing it to span significantly greater (1024 PiB instead of 16 TiB) volumes.ДЄssuming your target device is called /dev/mapper/target-device, this is what you need to do: You are attempting to resize a filesystem that was created before the -O 64bit option became default.
