Niveles de RAID. While I won't pretend to understand all the technical details, it is my understanding that fragmentation on ZFS doesn't mean quite the same thing that it does on other filesystems, and---I don't recall exactly where I saw this---fragmentation on a pool shouldn't start having a problematic impact until it reaches around 80%.

When using a NAS using Proxmox/ZFS, it makes more sense to manage quotas using ZFS filesystems and install multiple instances of Quickbox. -o ashift= is convenient, but it is flawed in that the creation of pools containing top level vdevs that have multiple optimal sector sizes require the use of multiple commands. 可以看到数据和快照都恢复好了. Es gibt einige klare Argumente einem ZFS Software Raid den Vorzug vor Hardware Raid zu geben, z. top has been updated to change the way the ZFS ARC compression ratio is calculated, and remove overhead statistics, already included in other counters.

The ZFS manual currently recommends the use of lz4 for a balance between performance and compression. With ashift=12 (4 kiB blocks on disk), the common case of a 4 kiB page size means that no compression algorithm can reduce I/O. # modprobe zfs # dmesg | grep ZFS [ 7446.
