Thanks All. we use JFS2 (on AIX5.2L). AIX docs say that it supports files as large as 16TB. that's too large. Raj>We have used 16GB at times ... but we use sushi files (raw not cooked) Raj,Hope u were in Japan for a while ;) from your experience, any suggestions for JFS2 ?? 2GB or 4GB or 8GB .... ?!!!
