No other file system supports shrinking the file system (whcih is what you are trying to do with resize2fs -M). And honestly, it's rare that people with very large file systems try to shrink file systems, which is why (a) most other file systems don't support it at all, and (b) it's not a super high priority for ext4 developers to try to track down.
If you are trying to grow the file system, that should work without problems (and in fact, given 1.42.5, I'd recommend using on-line resizing to grow file systems as oposed to off-line resizing, as there are a couple of bugs that weren't fixed until the very latest version of e2fsprogs). I asked last time someone complained about this problem (1) how much memory they had, and (2) did they have swap enabled, and (3) was this a 32-bit or 64-bit system? If you have a 64-bit system, and you have plenty of swap enabled, and you are still running into the problem and are willing to work with us a bit to try to debug the problem (which may require compiling the latest version of e2fsprogs from the git tree with some debugging code inserted), please contact the linux-ext4 mailing list directly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/455024 Title: resize2fs: memory allocation failed while trying to resize To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/455024/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
