Hi,
I am trying to understand how the open field is computed.
On a CentOS6 server, lvdisplay has the following output:
lvdisplay /dev/mapper/vg_obm-var_spool_imap
--- Logical volume ---
LV Path /dev/vg_obm/var_spool_imap
LV Name var_spool_imap
VG Name vg_obm
LV UUID
0oK7h0-tDZH-eUxE-AyBw-cK7x-U9pS-W7X4Uh
LV Write Access read/write
LV Creation host, time panoramix.ch-perrens.fr,
2015-01-16 11:03:10 +0100
LV Status available
# open 2
LV Size 1,92 TiB
Current LE 504572
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:3
And dmsetup show the following info:
# dmsetup info -c | grep "253" | grep " 3"
vg_obm-var_spool_imap 253 3 L--w 2
2 0
LVM-1i1v6pEjab2WslaDQRvkf8eLk6QfBW4J0oK7h0tDZHeUxEAyBwcK7xU9pSW7X4Uh
Could you please give me some hint to understand how "open = 2" is obtained ?
Regards
