The blkdeactivate now suppresses error messages from external tools that are called. Instead, only a summary message "done" or "skipped" is issued by blkdeactivate as any error in calling the external tool (e.g. unmounting or deactivating a device) causes the device to be skipped and the blkdeactivate continues with the next device in the tree. Add new -e/--errors switch to display any error messages from external tools. Also, suppress any output given by the external tools and add new -v/--verbose switch to display it including the verbose output of the tools called (this will enable error reporting as well). Also add blkdeactivate -vv for even more debug (the script's debug).

blkdeactivate \- utility to deactivate block devices
|
|
.SH SYNOPSIS
|
|
.B blkdeactivate
|
|
.RI [ options ]
|
|
.RI [ device... ]
|
|
.sp
|
|
.SH DESCRIPTION
|
|
blkdeactivate utility deactivates block devices. If a device
|
|
is mounted, the utility can unmount it automatically before
|
|
trying to deactivate. The utility currently supports
|
|
\fIdevice-mapper\fP devices, including \fILVM\fP volumes.
|
|
LVM volumes are handled directly using the \fIlvm\fP command.
|
|
Other device-mapper based devices are handled using the
|
|
\fIdmsetup\fP command.
|
|
.SH OPTIONS
|
|
.IP "\fB\-e, \-\-errors\fP"
|
|
Show errors reported from tools called by blkdeactivate.
|
|
Without this option, any error messages from these external tools
|
|
are suppressed and the blkdeactivate itself provides only a summary
|
|
message about device being skipped or not.
|
|
.IP "\fB\-h, \-\-help\fP"
|
|
Display the help text.
|
|
.IP "\fB\-u, \-\-umount\fP"
|
|
Unmount a mounted device before trying to deactivate it.
|
|
Without this option used, a device that is mounted is not deactivated.
|
|
.IP "\fB\-v, \-\-verbose\fP"
|
|
Run in verbose mode.
|
|
.IP "\fB\-d, \-\-dmoption\fP \fIdm_options\fP"
|
|
Comma separated list of device-mapper specific options.
|
|
.IP "\fB\-l, \-\-lvmoption\fP \fIlvm_options\fP"
|
|
Comma separated list of LVM specific options.
|
|
.SH DM_OPTIONS
|
|
.IP "\fBretry\fP"
|
|
Retry removal several times in case of failure.
|
|
.IP "\fBforce\fP"
|
|
Force device removal. See \fBdmsetup\fP(8) for more information.
|
|
.SH LVM_OPTIONS
|
|
.IP "\fBretry\fP"
|
|
Retry removal several times in case of failure.
|
|
.IP "\fBwholevg\fP"
|
|
Deactivate the whole LVM Volume Group when processing a Logical Volume.
|
|
Deactivating Volume Group as a whole takes less time than deactivating
|
|
each Logical Volume separately.
|
|
|
|
.SH EXAMPLES
|
|
.sp
|
|
Deactivate all supported block devices found in the system. If a device
|
|
is mounted, skip its deactivation.
|
|
.sp
|
|
.B blkdeactivate
|
|
|
|
Deactivate all supported block devices found in the system. If a device

|
|
.sp
|
|

|
|
.sp
|
|
.B blkdeactivate \-u /dev/vg/lvol0
|
|
|
|
Deactivate all supported block devices found in the system. Retry deactivation
|
|
of device-mapper devices in case the deactivation fails. Deactivate the whole
|

Volume Group at once when processing an LVM Logical Volume.
|
|
.sp
|
|
.B blkdeactivate \-u -d retry -l wholevg
