Is resize2fs safe?
This is the most time consuming one, and also the most dangerous (though it still should be reasonably safe). If possible (e.g., there is sufficient space), resize2fs makes the filesystem use only the first size bytes of the storage. It does this by moving both filesystem metadata and your data around.
Can you interrupt resize2fs?
First, resize2fs may take several hours or even more than a day to run, depending on the size of your partition. If you interrupted it while it was running, that’s a very good recipe for losing all your data. All of the filesystem data structures are probably in an inconsistent state.
Can ext4 be extended?
The size of Ext2, Ext3, and Ext4 file systems can be increased by using the resize2fs command when the file system is mounted. The size of an Ext3 file system can also be increased by using the resize2fs command when the file system is unmounted. If the file system is Ext2 or Ext4, you must unmount the file system.
What is the meaning of resize2fs?
Description. The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line resizing.
What’s the problem with resize2fs in Ubuntu?
The problem is that the resize2fs command doesn’t behave as expected. > sudo resize2fs /dev/vda1 resize2fs 1.42.12 (29-Aug-2014) The filesystem is already 7863561 (4k) blocks long. Nothing to do!
How big is the partition in resize2fs?
I rebooted using a live CD and I asked resize2fs to shrink the partition to a more reasonable size (50G), and it seemed to move data around pretty intensively in the first quarter of an hour or so (judging from the noise of the hard drive).
Why is resize2fs not working in offline mode?
Try to see if they are any (error) messages in the syslog. Your setup is simpler (no RAID1 LVM), so it should have taken way less time, and during the process, your hard disk will work a lot, not your CPU. Also, resize2fs has a -p flag (percentage), to display progression, but it is only in offline mode.
How to increase the size of an ext2 file system?
The resize2fs [ -fFpPM ] [ -d debug-flags ] [ -S RAID-stride ] device [ size ] command can resize ext2, ext3, or ext4 file systems. It is often used to increase or decrease the size of the unmounted file system. It can also be performed on the unmounted file system to expand its size.
