Hi, Once upon a time ( it was many years ago ) I had a backup server running debian Software Raid 1 on two 40 GB hard disks. As the backup Data size increased I upgraded it to two 80 GB hardisks still on debian software Raid 1. The choice of the OS was because I didnt know how to implement RAID on any of the BSDs then and also since there was no backuppc port for OpenBSD.
Later when the backup data size increased further I got an amd64machine with two 120 GB SATA drives. Unfortunately neither debian nor FreeBSD nor NetBSD recognized the disks. OpenBSD did reognize them and I some how managed to learn to implement RAIDFRAME with the help of Vijay Shanker from m...@openbsd. That was the first kernel re-compilation experience. Related docs below. http://openbsd-osnew.blogspot.com/2007/03/software-raid-on-openbsd-using.html http://openbsd-osnew.blogspot.com/2007/08/booting-from-raidframe-in-multiuser.html One Problem with OpenBSD was the large time it too to fsck the big /var partition after an unclean shutdown but it still was a robust system. One kind souls made an OpenBSD backuppc port and sent it to me offlist so OpenBSD became my happy backup server. Now the backup data size has further increased and I am planning to get 2 500GB hardisks to run raid 1 but I dont want to run OpenBSD because of the fsck problem after an unclean shutdown. 500 GB means a long wait. I was considering going back to debian with probably JFS on RAID 1 and LVM but then I thought of trying out FreeBSD and ZFS. It was then I heard about dragonfly and HammerFS. So I just want to know if anybody is using dragonfly and HammerFS in production. If you are how is your experience? I wouldn't want many file system snapshots but a stable file system because it will contain the backup data and less/no fsck time after an unclean shutdown. Also which version of backuppc does pkgsrc contain? And also since CCD and VINNUM are the only two ways Software RAID can be implemented on dragonfly which is a better one and how reliable are they compared to RAIDFRAME? thanks --Siju And since _______________________________________________ bsd-india mailing list [email protected] http://www.bsd-india.org/mailman/listinfo/bsd-india
