systemd seems to work fine after installing systemd-sysv (version 215-17+dev8u4) on debian 8 containers. Is there any reason I shouldn't use it?

Hi. I seem to be having a similar problem to Henry. I'm trying to install spacewalk on centos 7 using the guide from their documentation. In LXC containers, the script that sets up the database fails when trying to turn on postgresql, like so: [root@spacewalk ~]# systemctl enable...

As far as I can tell, especially with modern zfs versions, yes. Putting l2arc on a single point of failure will at worst cause zfs to read directly from your slower hard drives when that point fails. A non-mirrored zil, upon failure, will lose any data stored on the Zil and not on the hard...

I wouldn't call myself an expert, but this is how I understand it: ARC is a read-cache that wraps around the filesystem but isn't part of the filesystem itself, so it benefits from the performance of striping and doesn't benefit from the safety of mirroring. If the L2ARC fails, the data is...

By default proxmox gives half of the overall system memory to ARC, but the wiki shows how to limit its size. #limit ZFS arc to 4GB echo options zfs zfs_arc_max=4299967296 > /etc/modprobe.d/zfs.conf update-initramfs -u You'll need to reboot in order to get your memory back, and your storage...

Mirrored with backups it is then, for my own sanity. Thanks again.

I'm happy with the performance I've achieved, especially given the Evo's SLC cache. I'm more worried about performance degradation. Degradation is common in all SSDs, but there are horror stories on the internet about how not running TRIM will kill your drives fast. I am actually talking about...

Hey there. I've built a new proxmox 4 machine for the small business I work at, which will mostly be running a postgres database and a few web hosts in LXC, in addition to some windows kvm test environments, upgrading from an old Core 2 Quad system running PVE3.4 I'm using a pair of Samsung...
