pvs − report information about physical volumes
pvs [−a|−−all] [−−aligned] [−d|−−debug] [−h|−?|−−help] [−−ignorelockingfailure] [−−nameprefixes] [−−noheadings] [−−nosuffix] [−o|−−options [+]Field[,Field]] [−O|−−sort [+|-]Key1[,[+|-]Key2[,...]]] [−P|−−partial] [−−rows] [−−segments] [−−separator Separator] [−−unbuffered] [−−units hHbBsSkKmMgGtTpPeE] [−−unquoted] [−v|−−verbose] [−−version] [PhysicalVolume [PhysicalVolume...]]
pvs produces formatted output about physical volumes.
See lvm for common options. −−columns.
|
−−all |
Include information in the output about devices that have not been initialized with pvcreate. |
−−aligned
Use with −−separator to align the output columns.
−−nameprefixes
Add an "LVM2_" prefix plus the field name to the output. Useful with --noheadings to produce a list of field=value pairs that can be used to set environment variables (for example, in udev (7) rules).
−−noheadings
Suppress the headings line that is normally the first line of output. Useful if grepping the output.
−−nosuffix
Suppress the suffix on output sizes. Use with −−units (except h and H) if processing the output.
−o, −−options
Comma-separated ordered list of columns. Precede the list with ’+’ to append to the default selection of columns.
Use -o pv_all to select all physical volume columns, and -o pvseg_all to select all Physical Volume segment columns.
Use -o help to view the full list of columns available.
Column names include: pv_fmt, pv_uuid, dev_size, pv_name, pv_mda_free, pv_mda_size, pe_start, pv_size, pv_free, pv_used, pv_attr, pv_pe_count, pv_pe_alloc_count, pv_tags, pv_mda_count, pv_mda_used_count, pvseg_start, and pvseg_size.
With --segments, any "pvseg_" prefixes are optional; otherwise any "pv_" prefixes are optional. Columns mentioned in vgs (8) can also be chosen. The pv_attr bits are: (a)llocatable and e(x)ported.
−−segments
Produces one line of output for each contiguous allocation of space on each Physical Volume, showing the start (pvseg_start) and length (pvseg_size) in units of physical extents.
−O, −−sort
Comma-separated ordered list of columns to sort by. Replaces the default selection. Precede any column with - for a reverse sort on that column.
|
−−rows |
Output columns as rows. |
−−separator Separator
String to use to separate each column. Useful if grepping the output.
−−unbuffered
Produce output immediately without sorting or aligning the columns properly.
−−units hHbBsSkKmMgGtTpPeE
All sizes are output in these units: (h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Can also specify custom units e.g. −−units 3M
−−unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
