Print a list of the devices. For each device, display the device name, size, free available space, partitioning type, if it is marked as Shareable for Clustering, and if it is an NSS software RAID device. If no other options are specified, this prints a list of all devices and software RAID devices.
nlvm [-t] list devices [exclude] [more|all]
Command Options
Exclude the specified type of devices. This option can be used multiple times to add exclusions for different types. Valid device types are raid, nonraid, shared, nonshared, lvm, or nonlvm.
Example
exclude=raid exclude=nonshared
Use this NLVM option to format the output for parsing.
Prints more information than appears in the standard output. It can be used with or without the -t NLVM option.
Example
more
Prints detailed information about each of the devices. This is the same information that is printed for the nlvm list device <device_name> command. It can be used with or without the -t NLVM option.
Example
all
Command Example
Print detailed information for all non-LVM shared devices that are not software RAID devices.
You can issue the commands with the --terse NLVM option to output the same information in a format that is more easily parsed.
Standard Output
The command returns the following standard information about the devices on the server:
|
Label |
Description |
|---|---|
|
Name |
Device name such as sdb or raid1 |
|
Size |
Total amount of space on the device in KB, MB, GB, or TB |
|
Used |
Used space on the device in KB, MB, GB, or TB |
|
Free |
Available space on the device in KB, MB, GB, or TB |
|
Format |
MSDOS, GPT, CSM (legacy EVMS Cluster Segment Manager), LVM (clustered Linux LVM volume), None (not initialized) |
|
Shared |
Yes or No; whether this device is marked as Shareable for Clustering |
|
RAID |
Yes or No; whether this is an NSS software RAID device |
|
Enabled |
Yes or No; whether the RAID is enabled on this node |
More Output
The command returns the following additional information about the devices on the server:
|
Label |
Description |
|---|---|
|
RAID |
Type (0, 1, or 5) or No; type of NSS RAID device, or not a RAID |
|
Sync |
Yes or %; whether the RAID is in sync or percent completed |
|
M:M |
Major:Minor numbers, such as 8:112 |
|
SectorSize(logical/physical) |
Logical or physical sector size of a device |
|
Provisioning |
Thick or Thin provisioning type |
All Output
If the all option is used, the command returns the same information about each device as is displayed for the nlvm list device <device_name> command. This includes information about its partitions, or about its partitions and segments for RAID devices.
