Is it possible (or even supported) to run Zimbra Network Edition (latest version in the 4.5 series) on the JFS filesystem? I've done some searching around on Google as well as the Zimbra forums and wiki, but really the only slightly relevant info I've found was at /forums/administrators/10375-1-message-per-mailstore.html#post54426
I realize that Zimbra recommends ext3, but we've found in our company that JFS has some pretty significant performance benefits over ext3 and we'd like to run all JFS if possible. Has anyone done this? Does Zimbra use some specific features of ext3 that make it undesirable/impossible to run on another filesystem? Do we void our support with for the Network Edition by running on JFS?
