Ideal RAID-1 Stripe Size for IMAP Server ?
Hi there. I'm currently configuring a brand new email server(IMAP) which will run CentOS 6.3 x64. So lots of files on the data volume. I'm confused about stripe size for my data volume. I'm using 2x500GB for OS in RAID1 and 2x2TB SAS for DATA in RAID1 which is hosted on a HP Smart Array P420 Controller with 1GB in Cache/Battery Backed Up. Both these array's are on the P420 controller. The initial configuring from Array Configuration Tools gives me 256K in Strip Size. On both array's. What would be ideal for the d...

just logins now and shares later
...hat would be a reasonable size for user profiles on a 100MBit/s network so they load sufficiently speedy? Also should I consider something when I configure GPOs and printers some weeks after first user logins? Can I put home directories, shares, profiles and spooling on one 2TB disk on a RAID1 (2x2TB) or would this be a performance problem? (worst case scenario I can imagine is 5-8 simultaneous user logins or logouts which should happen very rarely. 2-3 simultaneus logins/logouts is more likely to happen frequently.) regards, birgit

JBOD / ZFS / Flash backed
Thanks, The 3 servers are new Lenovo units with redundant PS backed by two huge UPS units (on for each bank of power supplies). I think the chances of losing two nodes is incredibly slim, and in that case a Disaster Recovery from offsite backups would be reasonable. My requirements are about 2TB, highly available (so that I can reboot one of the 3 servers without taking down services). Beyond

Replication oddities - different sizes between replicated nodes
...r main host. I use hostA as my primary host. Both machines are located at Hetzner in Germany. HostA is in DC6 and HostB is in DC12. Not situated next to eachother but low latency links between them. Both machines are connected to gbit uplinks and are not very highly loaded. The machines consist of 2x2TB disk (mirrored with ZFS) and 8cores, 32GB RAM. There were warnings when manually doing the sync that the mailbox changed in between and should be reissued, after which the mailboxes kept growing. Previously I reported two messages here which might be the foundation of the same issue: https://dove...

Question about multiple RAIDZ vdevs using slices on the same disk
Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Best 1.5TB drives for consumer RAID?
Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would
