E2fsck
ask a question Anybody can answer The best answers are voted up and rise to the top Running out of memory running fsck on large filesystems up vote 9 down vote favorite 3 I look after an old Debian linux box (running etch) with only 512 MB of RAM, but a lot of external storage attached. One ext3 filesystem is 2.7 TB in size, and fsck can't check it, because it runs out of memory, with an error such as this one: Error allocating directory block array: Memory allocation failed e2fsck: aborted I've added a 4 GB swap partition and it still doesn't complete, but this is a 32-bit kernel, so I don't expect adding any more will help. Apart from booting into a 64-bit kernel, are there any other ways of getting fsck to complete its check? linux debian memory ext3 fsck share|improve this question asked May 17 '09 at 22:10 TimB 1,17521116 add a comment| 2 Answers 2 active oldest votes up vote 10 down vote accepted A 64 bit kernel and large quantities of RAM will allow the fsck to finish nice and fast. Alternately, there's now an option in e2fsck that'll tell it to store all of it's intermediate results in a directory instead of in RAM, which helps immensely. Create /etc/e2fsck.conf with the following contents: [scratch_files] directory = /var/cache/e2fsck (And, obviously, make sure that directory exists, and is on a partition with a good few GB of free space). e2fsck
system with insufficient RAM, you can encounter the following error. $ e2fsck -p -f /dev/vg_mnt/lv_mnt01 /dev/vg_mnt/lv_mnt01: Error allocating icount structure: Memory allocation failed /dev/vg_mnt/lv_mnt01: Error allocating directory block array: Memory allocation failed e2fsck: aborted This happens because the e2fsck tries to store all inode information in memory, which may exceed the available memory size on the system. To fix this, either upgrade the system with more memory or http://serverfault.com/questions/9218/running-out-of-memory-running-fsck-on-large-filesystems try to set additional options that allow e2fsck to create a temporary directory on a system with sufficient (several GB's) free disk space. Not that this only works for e2fsck version 1.40 or higher (meaning: CentOS and RHEL users are screwed since they only provide 1.39). $ rpm -qa | grep https://ma.ttias.be/e2fsck-error-allocating-directory-block-array-memory-allocation-failed/ e2fsprogs e2fsprogs-libs-1.39-34.el5_8.1 e2fsprogs-devel-1.39-34.el5_8.1 e2fsprogs-1.39-34.el5_8.1 To run the e2fsck with a recent version, try the following. $ cd /usr/local/src $ wget "http://kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/v1.42.5/e2fsprogs-1.42.5.tar.gz" $ tar xzf e2fsprogs-1.42.5.tar.gz $ rm -f e2fsprogs-1.42.5.tar.gz $ cd e2fsprogs-1.42.5 $ yum install gcc make $ ./configure $ make The above will download e2fsck (the latest version as of this writing), compile and make it but leave it in the directory of the build (/usr/local/src/e2fsck), it won't copy the binaries to your system. That means you can use the newly compiled binary at /usr/local/src/e2fsprogs-1.42.5/e2fsck/e2fsckw. Now, since you have a e2fsck version higher than 1.40, you can set the options to use a scratch-disk and avoice the Out-of-Memory errors. First, create the directory. $ mkdir -p /var/cache/e2fsck And create a custom file called /etc/e2fsck.conf that contains the following content. $ cat /etc/e2fsck.conf [scratch_files] directory = /var/cache/e2fsck This tells e2fsck to use a directory on disk if the total available
