When MARA Systems last played with reiserfs we found it quite sensitive to I/O errors. If a harddrive went bad then it easily could produce kernel panics, while ext2 just gave errors in most cases. Admittedly this was nearly three years ago and quite likely things most likely have improved considerably since then. Have not tested how ext3 behaves under such conditions. reiserfs however showed to be quite fast and space efficient, especially on small files quite commonly seen in a Squid cache. My view is that Reiserfs is fully mature for production use with Squid. I does not have any experience to tell how it compares in relation to XFS for Squid but is defeitely a plus compared to ext2. Have not tried ext3 for Squid workloads but I estimate ext3 to actually behave somewhat worse than ext2 for Squid and in addition have had some really bad experiences with the newer directory formats of ext3... but it might just be me who tries out new features too early.
