The container has 2 disk (raw format), the rootfs and an additional mount point, both of them are in ext4, I want to format to xfs the second mount point. Latency for both XFS and EXT4 were comparable in. Given that, EXT4 is the best fit for SOHO (Small Office/Home. From the documentation: The choice of a storage type will determine the format of the hard disk image. In Summary, ZFS, by contrast with EXT4, offers nearly unlimited capacity for data and metadata storage. directory" it will let you add the LVM and format it as ext4 or xfs If that does not work, just wipe the LVM off the disk and than try adding it. sdb is Proxmox and the rest are in a raidz zpool named Asgard. This is necessary should you make. aaron said: If you want your VMs to survive the failure of a disk you need some kind of RAID. Storage replication brings redundancy for guests using local storage and reduces migration time. If you're planning to use hardware RAID, then don't use ZFS. g. [root@redhat-sysadmin ~]# lvextend -l +100%FREE /dev/centos/root. That XFS performs best on fast storage and better hardware allowing more parallelism was my conclusion too. Then i manually setup proxmox and after that, i create a lv as a lvm-thin with the unused storage of the volume group. I was contemplating using the PERC H730 to configure six of the physical disks as a RAID10 virtual disk with two physical. 09 MB/s. ZFS also offers data integrity, not just physical redundancy.

This takes you to the Proxmox Virtual Environment Archive that stores ISO images and official documentation. I think it probably is a better choice for a single drive setup than ZFS, especially given its lower memory requirements. ZFS has a dataset (or pool) wise snapshots, this has to be done with XFS on a per filesystem level, which is not as fine-grained as with ZFS. This depends on the consumer-grade nature of your disk, which lacks any powerloss-protected writeback cache. ext4. Recently I needed to copy from REFS to XFS and then the backup chain (now on the XFS volume) needed to be upgraded. Features of the XFS and ZFS. • 2 yr.

For large sequential reads and writes XFS is a little bit better. LVM-Thin. Extend the filesystem. Both ext4 and XFS support this ability, so either filesystem is fine. Issue the following commands from the shell (Choose the node > shell): # lvremove /dev/pve/data # lvresize -l +100%FREE /dev/pve/root #. As you can see, this means that even a disk rated for up to 560K random write iops really maxes out at ~500 fsync/s. So the rootfs lv, as well as the log lv, is in each situation a normal. Proxmox VE can use local directories or locally mounted shares for storage. BTRFS. というのをベースにするとXFSが良い。 一般的にlinuxのブロックサイズは4kなので、xfsのほうが良さそう。 MySQLでページサイズ大きめならext4でもよい。xfsだとブロックサイズが大きくなるにつれて遅くなってる傾向が見える。The BTRFS RAID is not difficult at all to create or problematic, but up until now, OMV does not support BTRFS RAID creation or management through the webGUI, so you have to use the terminal. Roopee. However, to be honest, it’s not the best Linux file system comparing to other Linux file systems. Literally just making a new pool with ashift=12, a 100G zvol with default 4k block size, and mkfs. Both ext4 and XFS should be able to handle it. Outside of that discussion the question is about specifically the recovery speed of running fsck / xfs_repair against any volume formatted in xfs vs ext4, the backup part isnt really relevent back in the ext3 days on multi TB volumes u’d be running fsck for days!Now you can create an ext4 or xfs filesystem on the unused disk by navigating to Storage/Disks -> Directory. 3 XFS. Happy server building!In an other hand if i install proxmox backup server on ext4 inside a VM hosted directly on ZFS of proxmox VE i can use snapshot of the whole proxmox backup server or even zfs replication for maintenance purpose. It supports large file systems and provides excellent scalability and reliability. Run through the steps on their official instructions for making a USB installer.
