Vote and comment on its GitHub issue here: https://github.com/stratis-storage/stratisd/issues/72 I?m in favor of it. The daemon had to be there anyway, it makes sense to push SMART failure indicators up through the block layer into the volum...

Red Hat are working on a new user space wrapper and volume format based on md, device mapper, LVM, and XFS. http://stratis-storage.github.io/ https://stratis-storage.github.io/StratisSoftwareDesign.pdf It's an aggressive development schedule and as so much of it is journaling and CoW based I have no way to assess whether it ends up with its own set of problems, not dissimilar to Btrfs. We'll just have to see....

It looks like built-in RAID didn?t land in this version, which means we?re another 3-5 years from anything that actually works like ZFS or btrfs which are LVM + RAID + filesystem. According to the docs, you have to lay Stratis over MDRAID in EL8 to get storage redundancy:...

...it has to be rebuilt from scratch. Then you get a *new* bag of ugliness in the world. Software RAID systems, by contrast, evolve continuously, and so usually tend towards perfection. The same problem *can* come up in the software RAID world: witness how much wheel reinvention is going on in the Stratis project! The same amount of effort put into ZFS would have been a better use of everyone?s time. That option doesn?t even exist on the hardware RAID side, though. Every hardware RAID provider must develop their command line utilities and monitoring software de novo, because even if the Other Co...

*** This response is my personal opinion and may not reflect that of my employer. *** It seems recent updates to Anaconda and in particular Blivet in the CentOS 7 .iso are restricting things rather than expanding the options. We have a scenario where we are doing a CentOS 6 to CentOS 7 upgrade (replacement) using a backup partition to hold the install image. Over the years, as we added cloud

Hello list. The next days we are going to install Centos 7 on a new server, with 4*3Tb sata hdd as raid-5. We will use the graphical interface to install and set up raid. Do I have to consider anything before installation, because the disks are very large? Does the graphical use the parted to set/format the raid? I hope the above make sense. Thank you in advance.

...s secure or I should be away from it? scripted rsync. Simple, through ssh protocol and private key. No agent required on target. I use file level deduplication using hardlinks. To perform compression and block deduplication I could use fs like zfs (not available from epel) or use something like stratis (I don't checked if it offer deduplication in this moment). Encryption could be performed on fs level. Using a scripted rsync is the simpler way but there is something that could be leaved out by me (or undiscovered error). Simple to restore. BorgBackup is another solution similar to rsyn...
