Hi all! While I was having some fun, testing different filesystems at home and making some benchmarks, I hit a bug when running Postmark in an ext3 partition mounted with data=journal. I repeated this test twice and got the same results under Linux 2.5, also it was not found while mounting with data=writeback or data=ordered or under Linux 2.4. I don't know if it's a know problem or not, so I'm posting all the info...

Following the announcement on lkml, I have started using ext3 on one of my servers. Since the server in question is a farily security-sensitive box, my /usr partition is mounted read only except when I remount rw to install packages. I converted this partition to run ext3 with the mount options "nodev,ro,data=writeback,defaults" figuring that when I need to install new packages etc,

...netatalk, which graft together existing filesystems from multiple platforms. The book talks about the Ext3, JFS, the ReiserFS, and XFS journaling filesystems (overview, patching the kernel, administering, using, etc.). It also talks about OpenAFS and NFS.I also give some benchmark results (Bonnie, Postmark, etc.) to do some empirical comparison. This isn't purely a promotional posting - I'd sincerely appreciate feedback and suggestions if you know anyone who is trying to use one of these filesystems and needs a how-to book and a reference. This list is great for people who are already in the...

...s but falls apart on sequential transfer. xfs has great sequential transfer but really bad metadata ops, like 3 minutes to tar up the kernel. It would be nice if mke2fs would copy xfs''s code for optimal layout on a software raid. The mkfs defaults and the mdadm defaults interact badly. Postmark is somewhat bogus benchmark with some obvious quantization problems. Regards, jwb

This is a recent benchmarking using Postmark which supposedly simulates mail servers.

Everyone, I am putting together a new mail server for our firm using a SuperMicro with Centos 7.0. When performed the install of the os, I put 16 gigs of memory in the wrong slots on the mother board which caused the SuperMicro to recognize 8 gigs instead of 16 gigs. When I installed Centos 7.0, this error made the swap file 8070 megs instead of what I would have expected to be a over 16000

After compiling and running the kernel I created an ext3-file system on an 70GB LVM.

...started with 2.4.20, and managed to tickle the "buffer credits" bug reported here: http://www.spinics.net/lists/ext3/msg02297.html So we went to 2.4.21 and 2.4.22, as they include the patch reported in the above message. But we're still getting the bug. We can reproduce it using postmark inside versionfs, mounted on top of ext3, in 2.4.22: kernel: Assertion failure in do_get_write_access() at transaction.c:720: "handle->h_buffer_credits > 0" Now, it's quite possible that we're not doing something right in versionfs which messes ext3 up. We're unabl...

Hi All, I run a little hosting company. I use Dovecot 1.0.10* with IMAP exclusively. Lots of my customers use Outlook or Outlook Express. This poses a problem. These programs don't and have absolutely no workarounds to move messages to a trash folder when deleted. They only mark the message for deletion. Then, users have to purge the message to actually delete it. Outlook has a way
