Online reduce of reiserfs file system

You will see that LV is 1 GB bigger than the filesystem. So now we have to resize the filesystem to be able to use all the space available in the LV.

Working with storage is always risky, but this kind of operations are specially dangerous. But at this point, it would be worth checking it. The order we are going to follow to decrease the size is more or less the opposite we did in the last section. Review the amount of space available in the filesystem and make sure there is more free space that the amount of space you want to reduce. Unfortunately, reducing the filesystem size in ReiserFS is not implemented.

So, we will have to unmount it. Remember this to plan this tasks if you are working on a production environment. It is time to reduce the filesystem. Now we can reduce the size of our logical volume. As you have already guessed, we can reduce less or equal space than the reduced in the last step. It is only left to mount the volume again and we will see the new size.

Reiser File System Reiser3 and Reiser4. Thread starter Jarret W. Buse Start date Aug 7, Jarret W. Buse Guest. Reiser3 was the first Journaling file system included in the Linux Kernel. Reiser4 was introduced in which was an improved Reiser3 file system. When the file system is mounted and a previous crash is detected, the recovery of the items in the Journal is automatic. When disk space is running low on a Resier3 volume, it is possible to perform an Online Resizing to increase the free space.

Extra space is created by using unused partitions on other hard disks. Jump to: navigation , search. Category : ReiserFS. Views Page Discussion View source History.
