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/
