[opensuse] Where did my free space go?
Hi, once 10.2 was released I installed it on my laptop using ext3 instead of reiserfs to avoid support issues. Now comes the issue, my home filesystem has 56GB of which i used 53GB, BUT the free space states 41MB. So, where are the other 3GB?. Already tried with a du -hs /home/ and i still get 53GB of usage. Tried also to unmount and run fsck, but apparently all is good. Any thoughts?

A file system is divided into blocks. When you create a 1 byte file, you will use up one entire block. Essentially you lose the remaining bits (unless you have a file system that can put multiple files into one block, like reiserfs) In ext3, the default block size is 4k, so when you create a one byte file, you lose 4095 bytes, My guess is that this is what has happened to your 3GB. If you have a high number of files that don't fill up their blocks, say 3 million files that each lose 1k each, that's 3GB gone Anders -- Madness takes its toll -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

One more thing that I forgot: in ext3, a certain percentage is reserved for administrative use. By default this is 5%, and that is 2.8GB out of 56, which would account for a lot of the difference.

Totally forgot about it!, too much time with reiserfs and zfs :p Thanks a lot Ciro -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Ext3 reserves 5% of the available disk space for root. Thereby, it is ensured that root can log in even if a user "filled" the whole disk. However, this does not make sense on your seperate home partition since root does not use it as its home: http://wiki.archlinux.org/index.php/Ext3_Filesystem_Tips#Reclaim_Reserved_Fi... Nonetheless, fillung up a partition above ~85% is considered harmful to performance due to fragmentation!

Thanks, already fixed it.

Well, it's my laptop (not high end server) and would like to use every GB I paid for :p

That's odd, I must have missed the part where suse said they won't support reiserfs any more. I'm running all my 10.3 installs on reiser with no problems. The suse enterprise 10 servers I installed a couple weeks ago defaulted to reiser too, come to think of it. Could you explain what your support concerns were? Sorry, I don't have an answer on the ext3 woes, as I don't use ext3. No doubt others here can speak directly to the issue.

There was a controversy about this long ago. The only verifiable thing is that suse said that reiserfs was not going to be their default filesystem in the future; they never said it was not going to be supported.

I love reiserfs (when not used with big files), all the SLES servers that i manage still use it. I was talking about long term support issues as i'm not sure when i'll reinstall my laptop.

We will support reiserfs, it's just not the default anymore. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
