    resize of large ext4 filesystem with resize2fs does not work

    I have also reported this as a bug to ubuntu https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1321958 It might also be interesting if this is solved again in the very new 1.42.10 I did also try to let it run with all debug flags set. This did cause endless terminal output of...

    resize of large ext4 filesystem with resize2fs does not work

    Hi, So I was brave and tried as hundlos has proposed: - I removed e2fsprogs using apt-get although it was quite reluctant to do so and gave some scary warnings - downloaded the tar.gz of e2fsprogs 1.42.8 from sourceforge - compiled according to the instructions that came with it -...

    resize of large ext4 filesystem with resize2fs does not work

    Hi hundlos, This sounds intersting. How did you do the downgrade? Did you use the tar.gz package from sourceforge or is there a way to tell the ubunto packet manager to downgrade to a previous version? Is there anything I need to consider or avoid in the process? best regards, Joerg

    resize of large ext4 filesystem with resize2fs does not work

    Hi brutalizer, I agree, huge datacenters with hundreds of disks would create reasonable sized arrays and then combine them to volumes/pools. However, my small home server use case is different. I have a small number of disks and occasionally want to add another disk to increase space. All disks...

    resize of large ext4 filesystem with resize2fs does not work

I will try the following: 1. use the very latest e2fsprogs 1.42.10 2. I will install another unix version, Maybe Debian or Fedora, and try the rezise there...

    resize of large ext4 filesystem with resize2fs does not work

    Hi ezno_matrix, Yes, I tried with and without the -S option. I also tried the debug levels, but only to get a lot of output I do not reall;y have an idea what iot means. I did also not find much information about it. The good thing is that it seems to be ok to stop the rezise process any time...

    resize of large ext4 filesystem with resize2fs does not work

    Hi, Thanks for the answers. I did never have any problems with ext4 until now. When I built the 20TB array last summer I even tested growing above the 16TB limit and it worked. If I remember correctly, ZFS for linux was last summer just out with a somehow stable version and thus on Linux...

    resize of large ext4 filesystem with resize2fs does not work

    Hi ezno_matrix, Thanks for your answer. I actually use the -S option and I agree, that I would expect that this only takes a few minutes to finish. All the other times in the past when I was using rezise2fs, it was quite fast. But that is the problem, The command is running now for many hours...

    resize of large ext4 filesystem with resize2fs does not work

    Hi, I hope somebody can help me with an issue I have rezising a filesystem using resize2fs with ubuntu 14.04. I am extending a RAID 6 using mdadm. I did add 2 additional disks which did extend the array size from 20TB to 28TB. Reshaping the array has finished without problems. Now I have...

    create ext4 to allow growth above 16TB

    Hi, There was a lot of discussions regarding the usage of ext4 filesystems beyond 16TB in recent months here and also in other places. I as far as I understood it is not possible to resize an ext4 filesystem that was created smaller than 16TB to a size bigger than 16TB. This is because the...
