2020年6月28日 · And for experienced users, who know raid and backup strategies well enough to make a good decision if a raid0 is a good option for the use case or not, it shouldn't be a big problem running the three oneliners to create the raid0 pool and add it as storage to PVE:

2024年3月31日 · Da hast du dann aber hakt auch keine anspruchsvollen CoW-Dateisysteme wie ZFS, üblicherweise kein Raid, kein Virtualisierungsoverhead, keine verschachtelten Dateisysteme, weniger DBs die viele Sync Writes absetzen, keine gemischten Blockgrößen, ... Billige consumer SSD ohne DRAM-Cache: kann weder async noch sync writes cachen/optimieren

2021年2月20日 · "ZFS Raid 1" heißt "ZFS mirror" und kann aus 2-x Platten bestehen, wobei die Anzahl meistens gerade ist (zB bei 3 jedoch nicht, ist dann aber halt ein 3fach mirror). Ein HW-raid1 besteht aus 2 Platten, darüber hinaus ist es ein Raid10 mit gerade Anzahl (zB 10), ist aber eher selten, weil man da eher in Richtung Raid6 (oder bei sehr vielen ...

2025年1月2日 · As for software raid options with pbs, I benchmarked zfs and btrfs. btrfs consumes less cpu and much less RAM than zfs. It also came on top for effective throughput. I tried to tweak the benchmark to account for the very specific load of pbs, a continuous stream of files, sizes between 1Mbytes and 4Mbytes.

2024年4月2日 · Benefit of ZFS for SW raid for example would be that you are not screwed once your hardware fails or if you want to upgrade your server, as ZFS will work on any machine and with HW raid you are forced to replace the hardware with one that uses the same (or at least a compatible) HW raid controller. Otherwise you won't be able to access your data.

2021年2月2日 · - send the entire poll via zfs send/receive(or pve-zsync) on a different host(DF) with zfs - export the zpool history to a file and keep it on other system - destroy the hddpool

2022年5月27日 · ZFS for example will write the data to disk before returning a success message by default using synced writes. The admin can add SSD/NVMe drives and configure to cache writes before writing to disk to speed things up, but be just as secure if …

2022年1月24日 · The Hardware RAID controller is a PERC H730 Integrated RAID Controller with 1GB Cache. I am running 8X1 TB SanDisk SSD Plus 1TB Internal SSD - SATA III 6Gb/s. I am quite familiar with ZFS, as I use it on my TrueNAS instance (ZFS-2). So, I am trying to decide if I run the native RAID-5 with the hardware controller for Proxmox, or use ZFS-2 in ...

2021年2月5日 · Whether running ZFS or RAID+LVM, a big challenge is tuning it for your workload. Also, if you plan on expanding the array by adding or deleting drives later, that may impact your decisions. One of the biggest downsides to traditional RAID is that all the drives should be the same speed, and the partitions need to be the same size on each drive.

2022年5月28日 · If it's option A, then just replace the fake disk. Otherwise expanding with 3 disks is impossible. If you get another drive you can add that as a mirror to the pool. Striped mirror aka raid 10. Not the best imo since a raid Z2 is guaranteed 2 drive failures while striped mirror is only guaranteed 1 and MIGHT save you from 2.
