vzlist
- example:
vzlist CTID NPROC STATUS IP_ADDR HOSTNAME 101 26 running - localhost.fantinibakery.com 102 121 running 10.100.100.18 mediawiki.fantinibakery.com 114 49 running - fbc14.fantinibakery.com
From PVE 3.0 onwards, the display will be:
vzlist CTID NPROC STATUS IP_ADDR HOSTNAME 101 26 running - localhost 102 121 running 10.100.100.18 mediawiki 114 49 running - fbc14
- The fields for selective display are: ctid, nproc, status, ip, hostname.
- All are case sensitive and are used with the options -H (no header) and -o [field1, field2, ...]
- The binary is at: /usr/sbin/vzlist
USAGE
Usage: vzlist [-a | -S] [-n] [-H] [-o field[,field...] | -1] [-s [-]field] [-h pattern] [-N pattern] [-d pattern] [CTID [CTID ...]] vzlist -L | --list Options: -a, --all list all containers -S, --stopped list stopped containers -n, --name display containers' names -H, --no-header suppress columns header -t, --no-trim do not trim long values -j, --json output in JSON format -o, --output output only specified fields -1 synonym for -H -octid -s, --sort sort by the specified field ('-field' to reverse sort order) -h, --hostname filter CTs by hostname pattern -N, --name_filter filter CTs by name pattern -d, --description filter CTs by description pattern -L, --list get possible field names
Backup

Cluster management
pveca
PVE Cluster Administration Toolkit
USAGE
- pveca -l # show cluster status

- pveca -s [-h IP] # sync cluster configuration from master (or IP)
- pveca -d ID # delete a node
- pveca -a [-h IP] # add new node to cluster
- pveca -m # force local node to become master
- pveca -i # print node info (CID NAME IP ROLE)
Software version check
pveversion
Proxmox VE version info - Print version information for Proxmox VE packages.
USAGE
pveversion [--verbose]
- without any argument shows the version of pve-manager, something like:
- pve-manager/1.5/4660
or
- pve-manager/3.0/957f0862
- with -v argument it shows a list of programs versions related to pve, like:

LVM
Most of the commands in LVM are very similar to each other. Each valid command is preceded by one of the following:
- Physical Volume = pv
- Volume Group = vg
- Logical Volume = lv

pveperf
Simple host performance test.
(from man page)
USAGE
- pveperf [PATH]
DESCRIPTION
- Tries to gather some CPU/Hardisk performance data on the hardisk mounted at PATH (/ is used as default)
It dumps on the terminal:
- CPU BOGOMIPS: bogomips sum of all CPUs
- REGEX/SECOND: regular expressions per second (perl performance test), should be above 300000
- HD SIZE: harddisk size
- BUFFERED READS: simple HD read test. Modern HDs should reach at least 40 MB/sec
- AVERAGE SEEK TIME: tests average seek time. Fast SCSI HDs reach values < 8 milliseconds. Common IDE/SATA disks get values from 15 to 20 ms.
- FSYNCS/SECOND: value should be greater than 200 (you should enable "write back" cache mode on you RAID controller - needs a battery backed cache (BBWC)).
- DNS EXT: average time to resolve an external DNS name
- DNS INT: average time to resolve a local DNS name
Note: this command may require root privileges (or sudo) to run, otherwise you get an error after "HD SIZE" value, like: <<sh: /proc/sys/vm/drop_caches: Permission denied unable to open HD at /usr/bin/pveperf line 149.>>
