zfs

Hi everyone, I'm looking for advice on how to get the most performance out of my hardware. I have a Lenovo ST250 with a RAID 530-8i controller (flashing to IT mode is not an option). My disk setup is as follows: 1. 1x Intel 4520 M.2 SATA SSD (480GB) 2. 4x SAS 10K 12Gbps (900GB) 3. 2x SAS...

I have a fast 2TB NVME SSD and a slow 4TB SATA SSD inside a RAID0 zfs zpool. I like zfs (over lvm which I had before) for its versatility in managing storage (e.g. one pool to use, including the pve root), however I'm running into the issue that my mixed hardware slows down. With LVM, I could...

Hello, Last night I had to shutdown my server during a power outage. Prior to shutting down, everything was working as normal. I was able to do a safe shutdown before the UPS ran out of juice. This morning I turned everything back on, and since then I have been receiving a "Failed to initialize...

Hi there, I have two Proxmox VE 8 servers called proxmox1 and proxmox3. The backups of proxmox1 are validated every night (copy to Debian desktop, decompress, start and ping). Proxmox3 is an old Dell Precision T1650 meant to serve as backup in case proxmox1 fails. It has a 512MB NvMe on a...

I had to break my 3-way mirror because the amount of available space was inadequate. Somehow my calculations for the total amount of required usable space was woefully off, but that is a separate discussion. I now have a RAIDZ1, with no quotas or reservations, on this or any other dataset...

The Linux runtime power management (RPM) provides everything necessary to put unused disks to sleep and wake them up when required. If properly configured this can save energy in SOHO environments where disks often idle in the night and during non office hours. However, a major drawback when...

Hallo. Diese Frage läuft sicher nicht zum ersten Mal ... aber ich möchte sie trotzdem nochmal stellen, da ich die Größenangaben bei Verwendung von ZFS-Pools weiterhin verwirrend finde. Die Situtation ist: IBM-M4-Server mit 4 Platten zu einem Z2-Pool (mit Cache). Unter Disks -> ZFS sehe ich...
