Re: [pve-devel] [PVE-User] Proxmox VE 3.4 released!
Some questions:
1) if I have an HA cluster, does ZFS get me anything? Or is it really
only useful for standalone systems using local storage?
only useful for local storage
2) to get root-on-zfs, I assume I must reinstall instead of upgrading?
yes
3) since I use CEPH and only have 3 hard disks per server, I assume I
cannot use ZRAID{,2} and still have the host be a CEPH OSD? (i.e. CEPH
continues to require dedicated disks?)
For ZRAID2, you need at least 4 disks, plus another SSD for L2ARC ...
And yes, ceph needs decicated disks.

Oh, I forgot the most important part! It is much better to create pools referencing to disks by id, instead of their names: it is hard to recover in any situation or just move from one server to an other. Like this: zpool create -f -o ashift=12 rpool mirror /dev/disk/by-id/scsi-SATA_VBOX_HARDDISK_VB36f143cd-f66be985 scsi-SATA_VBOX_HARDDISK_VB65ee0fc1-be50526b mirror scsi-SATA_VBOX_HARDDISK_VBa9dd99c6-905d92f0 scsi-SATA_VBOX_HARDDISK_VBf8fa61c8-3707c5fe Unfortunately, I was not able to get that work inside the busybox environment we use for the installer. ___ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel

- it use gzip-6 compression by default - as the system supports lz4 compression, I recommend to use this one instead of gzip-X. In general. Of course, it is possible to change the compression on the fly (for newly written blocks) but for general usage, lz4 needs less power and provides a really nice compressratio. Oh, I was not aware of the. Will change that. ___ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
