可以基于文件系统设置压缩: trochej@madchamber:~$ sudo zfs get compression data/datafs NAME PROPERTY VALUE SOURCE data/datafs compression on local trochej@madchamber:~$ sudo zfs set compression=on data/datafs 压缩比可以通过查询一个属性来确定: trochej@madchamber:~$ sudo zfs get compressratio ...
sudo zfs set compression=lz4 nas2可以查看zfs阵列的压缩率:zfs get compressratio nas2输出内容大致如下:NAME PROPERTY VALUE SOURCE nas2 compressratio 1.12x -值得注意的是,如果你的阵列是新建不久,里面还没有多少文件时,一般这个值是1。压缩率与文件类型有很大的关系。比如,lz4对视频格式的压缩程度是不高的...
compression replication snapshot zfs Replies: 0 Forum: StorageDataset with path /mnt/<PoolName> not found I needed to clone a pool from one drive onto a new pool on a second drive. I followed this guide to do this. Now when I try to click any link in the UI, I get a blank ...
对于本地文件系统系统,支持Quota,Reservation,Compression 并不难,对于用COW技术,Snapshot,Clone几乎是COW的附带的产品,实现都很容易。 9)ZFS的容量无限制。 他是如何做到的呢?一个就是ZPOOL, 这使得容量可以动态扩展,其次,元数据也是动态分配的,也就是inode也是动态分配的。 对于本地文件系统,我们说的扩展性,这的...

Both seems to me configured equally (eg, for example, no compression). I've read:https://pve.proxmox.com/wiki/ZFS_on_Linux#sysadmin_zfs_raid_considerationsbut really i'm got a bit lost... there's somewhere a more clear explanation of the 'effect', and i hope some parameters to tackl...
performance while providing decent data compression. Setting compression to on uses the lzjb compression algorithm. The gzip compression algorithm uses the same compression as the gzip(1) command. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) ...
The zfsadm compress command is a long-running administrative command that uses the zEDC compression method to compress an existing zFS aggregate. To improve performance of the compression I/O, IBM recommends that you specify the edcfixed option in the IOEFSPRM parameter user_cache_size. If ...
