comment NFS on Btrfs on multi-devices .vs. Glusterfs on distributed-volume?
I want to hide complicated below, and only use volume (of OpenStack) as disk. When my mail storage nearly full, i simply create new volume and attach it to server. Therefore, i need a FS that can combine multi-drives Safe(not lose data on any situation) & Efficient(fast "enough"). I think about few options like: Ext4 on LVM, Btrfs on multi-devices, Glusterfs with distributed-volume, mhddfs, unionfs, aufs,... Which do you think it's best for my use-case? Thank you!

I need to export storage over something like NFS or Glusterfs because this will be mounted on multi dovecot server.

"private cloud" means i'm running on OpenStack, and my "disk" is volume of Openstack.

comment Convert PUB key to PKCS8 format on CentOS?
"Normally a PKCS#8 private key is expected on input and a traditional format private key will be written. With the -topk8 option the situation is reversed: it reads a traditional format private key and writes a PKCS#8 format key." <-- I want convert public key, not private key. (PS: i use command you suggest, but it eror: "unable to load key")

@ewwhite: my RAID controller does not have battery-backed. Should i disable "Write-cache mode" instead?

hi, i use maildir, and normally i receive > 100 mails/day (from colleagues, partners, customers and from monitoring system) --> 50,000 mails/year. I don't assume that my email users will delete emails or reorganize it into folders, we can not sure about it.

I read something and find that xfs & btrfs is not safe on power outage, can lose much of data. You could confirm it? Thanks!
