A Suse resellers told me that by using LVM I can do hot backups on my openexchange email server. I was told that by using LVM I can take snapshots of my LVM and use that for my backup with Arkeia backup software. I am not at all familiar with LVM though I understand the general concept behind LVM. Here is what I don't know after googling for a while.
How the heck can LVM be used with a RAID 5 setup?
Does anyone use LVM on a production server?
Does anyone have any opinions about using LVM on mission critical servers?
Right now I'm trying to weigh out if its worth the trouble to do hot backups for this particular server. The backups I'm predicting will take somewhere along the time frame of 1-2 hours. Arkeia is claiming they will be releasing a new version of there backup software for linux that will solve this problem sometime in the future.
I am planning ahead for my install of Suse on a poweredge 2650
raid 5 with 4 36gig HD's. I see allot of users doing this type of thing
/tmp=2gigs
/home=30 gigs
/var=30 gigs
/=5 gigs
/boot=100mb
swap=1 gig
....
....
....
I have in the past only did
/boot
/
swap
Is there any Performance advantage to creating a partition for everything? What is the major benefit in doing this?
Thanks,
