lvs - report information about logical volumes

lvs produces formatted output about logical volumes.  


See lvm(8) for common options.
Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as mirrors, but which are not independently accessible (e.g. not mountable). The names of such Logical Volumes are enclosed within square brackets in the output. For example, after creating a mirror using 'lvcreate -m1 --mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
Use with --separator to align the output columns.
-o, --options
Comma-separated ordered list of columns. Precede the list with '+' to append to the default selection of columns instead of replacing it.
Use -o lv_all to select all logical volume columns, and -o seg_all to select all logical volume segment columns.
Column names include: chunk_size, convert_lv, copy_percent, data_lv, devices, lv_attr, lv_host, lv_kernel_major, lv_kernel_minor, lv_kernel_read_ahead, lv_major, lv_minor, lv_name, lv_path, lv_read_ahead, lv_size, lv_tags, lv_time, lv_uuid, metadata_lv, mirror_log, modules, move_pv, origin, origin_size, pool_lv, region_size, segtype, seg_count, seg_pe_ranges, seg_size, seg_start, seg_start_pe, seg_tags, snap_percent, stripes, stripe_size, thin_count, transaction_id, zero.
With --segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are optional. Columns mentioned in vgs(8) can also be chosen.
The lv_attr bits are:
Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin, (O)rigin with merging snapshot, (r)aid, (R)aid without initial sync, (s)napshot, merging (S)napshot, (p)vmove, (v)irtual, mirror or raid (i)mage, mirror or raid (I)mage out-of-sync, mirror (l)og device, under (c)onversion, thin (V)olume, (t)hin pool, (T)hin pool data, raid or thin pool m(e)tadata
Permissions: (w)riteable, (r)ead-only, (R)ead-only activation of non-read-only volume
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited This is capitalised if the volume is currently locked against allocation changes, for example during pvmove(8).
fixed (m)inor
State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended snapshot, snapshot (m)erge failed, suspended snapshot (M)erge failed, mapped (d)evice present without tables, mapped device present with (i)nactive table
device (o)pen
Target type: (m)irror, (r)aid, (s)napshot, (t)hin, (u)nknown, (v)irtual. This groups logical volumes related to the same kernel target together. So, for example, mirror images, mirror logs as well as mirrors themselves appear as (m) if they use the original device-mapper mirror kernel driver; whereas the raid equivalents using the md raid kernel driver all appear as (r). Snapshots using the original device-mapper driver appear as (s); whereas snapshots of thin volumes using the new thin provisioning driver appear as (t).
Newly-allocated data blocks are overwritten with blocks of (z)eroes before use.
Use default columns that emphasize segment information.
-O, --sort
Output columns as rows.
--separator Separator
Produce output immediately without sorting or aligning the columns properly.
