What is the status of Gjournal? X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 17 Aug 2007 01:28:52 -0000 With ZFS, I have not seen much new going on with gjournal. I am curious what the status of gjournal and if it will likely be included with 6.3 (whenever that is due) Also, as of late, I have been using it with 6.2-STABLE via the patches and I seem to be getting 1/2 the transfer speeds compared to non journaled disks. It seems like this is recent as previous tests showed it as quite fast. Any suggestions on why this could be happening greatly appreciated. tested via dd if=/dev/zero of=./testfile bs=16 count=16384 On 2 different dual opteron systems with 8 gigs of Ram running FreeBSD 6.2-STABLE amd64 (as of 4 days ago) Regardless of the disk (I tested scsi and ata and one on a raid controller) both times I converted it to journal, the speed went in half. With disks getting larger and larger, why is it taking so long for a journaled filesystem to be standard on BSD? Thanks! Nicole
