On Solaris you would typically use logical volumes created with Veritas LVM.

Usually you would use a symlink to such a raw device if such a device needs to be in /dev. > I guess there would need to be a system table that keeps track of > (dev, offset, size) tuples for each WAL file. This would need to be hidden in a new smgr layer. Andreas ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
