I can't help with TSM/DB2 on Linux, but we run vcs/vxvm/vxfs on AIX for our big oracle databases. I asked one of the admins what they did and here is his response.

Veritas Cluster Services is the standard clustering software in our company for physical Linux servers. Our new TSM design is also based on VCS with a mirrored containerpool on IBM v5010 storage. Does anybody have experience with performance tuning on VCS or the VxFS filesystem in combination with TSM? Any tips you like to share? Thank you very much for your help in advance!
