您可以使用zfs userspace （和zfs groupspace ）来执行此操作，该操作会显示文件系统中的所有用户（即文件的当前所有者）或文件系统中的配额（由zfs set userquota ） 。 请注意，它不是recursion的（类似于zfs list ，因此您可能需要为每个子文件系统调用它。

示例shell脚本

 #!/bin/ksh # get all children file systems from given file system argument filesystems=$(zfs list -Hro name "${1}") # get all space usage line by line in the format # <usedspace>\t<userquota>\t<username>\t<filesystem>\n # (it can later be sorted by the first column) for filesystem in ${filesystems}; do sizes=$(zfs userspace -Hp -o used,quota,name "${filesystem}") IFS=$'\n' # multi-line output of userspace makes inner loop necessary for size in ${sizes}; do printf "%s\\t%s\\n" "${size}" "${filesystem}" done unset IFS done 

输出示例

 root@host:/root# ./test.sh rpool | sort -rn cannot get used/quota for rpool/dump: dataset is busy cannot get used/quota for rpool/swap: dataset is busy 4273131520 none root rpool/ROOT/omnios-2 4197847040 none root rpool/ROOT/omnios-1 2681162240 none root rpool/ROOT/omnios [...]

  zfs userspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot Displays space consumed by, and quotas on, each user in the specified filesystem or snapshot. This corresponds to the userused@user and userquota@user properties. -H Do not print headers, use tab-delimited output. -S field Sort by this field in reverse order. See -s. -i Translate SID to POSIX ID. The POSIX ID may be ephemeral if no mapping exists. Normal POSIX interfaces (for example, stat(2), ls -l) perform this translation, so the -i option allows the output from zfs userspace to be compared directly with those utilities. However, -i may lead to confusion if some files were created by an SMB user before a SMB-to-POSIX name mapping was established. In such a case, some files will be owned by the SMB entity and some by the POSIX entity. However, the -i option will report that the POSIX entity has the total usage and quota for both. -n Print numeric ID instead of user/group name. -o field[,field]... Display only the specified fields from the following set: type, name, used, quota. The default is to display all fields. -p Use exact (parsable) numeric output. -s field Sort output by this field. The -s and -S flags may be specified multiple times to sort first by one field, then by another. The default is -s type -s name. -t type[,type]... Print only the specified types from the following set: all, posixuser, smbuser, posixgroup, smbgroup. The default is -t posixuser,smbuser. The default can be changed to include group types. zfs groupspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot Displays space consumed by, and quotas on, each group in the specified filesystem or snapshot. This subcommand is identical to zfs userspace, except that the default types to display are -t posixgroup,smbgroup.
