| 23:16 | tidux has joined IRC (tidux!~tidux@mab.sdf.org) | |
| 23:18 | <tidux> Is there a good documentation source on using NBD instead of NFS? I'm looking on the ltsp.org website and can't find it.
| |
| 23:18 | I've never used NBD but I know from running VMware clusters that block-level (iSCSI) typically beats file-level (NFS) network stores
| |
| 23:25 | <vagrantc> alkisg had some reliability issues with NBD and so switched to an image shipped over NFS ... slight performance loss but much higher reliability.
| |
| 23:25 | <tidux> good to know
| |
| 23:25 | <vagrantc> for quite some time LTSP used NBD by default ...
| |
| 23:26 | long ago it used the rootfs directly over NFS ... now it's using a squashfs image mounted from an NFS volume... seems to work better
| |
| 23:27 | i've seen some patches for LTSP fly around for using ceph/rbd instead, which probably has more active maintenence than NBD
| |
| 23:27 | <tidux> oh yeah ceph blockdevs would be ideal
| |
| 23:27 | especially squashfs+ceph for root
| |
| 23:28 | <vagrantc> and in theory, iSCSI might be an option ... alkisg also experimented with Ata-over-Ethernet (AoE) which had some interesting features
| |
| 23:28 | <tidux> iSCSI is mostly useful for people with existing proprietary SAN setups. If you're building fresh for an all-Linux system, I'd go with Ceph.
| |
| 23:29 | <vagrantc> you can probably experiment around with hooks in the initramfs; LTSP doesn't much care where it gets it's root filesystem from
