LVMSADC(8)						      System Manager's Manual							LVMSADC(8)

NAME
lvmsadc - LVM system activity data collector SYNOPSIS
lvmsadc [-d|--debug] [-h|--help] [-v|--verbose] [LogFilePath] DESCRIPTION
lvmsadc collects the read/write statistics of the logical volume manager to the file "LogFilePath" or to stdout if no LogFilePath is given. If you want to have I/O statistics at hand for performance tuning, you should create a cron entry for lvmsadc which runs it at regular intervals eg. 10 minutes. You need to take care of size control of the log file yourself! OPTIONS -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about lvmsadc's activities. DIAGNOSTICS
lvmsadc returns an exit code of 0 for success or > 0 for error: 1 no log file path and name on command line 2 error opening log file for append 3 no volume groups found for data collection 4 error closing log file 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line See also lvm(8), lvmsar(8) AUTHOR

lvscan [-b|--blockdevice] [-d|--debug] [-D|--disk] [-h|--help] [-v|--verbose] DESCRIPTION
lvscan scans all known volume groups or all supported LVM block devices in the system for defined logical volumes. OPTIONS -b, --blockdevice Adds the device major and minor numbers to the display of each logical volume. -d, --debug Enables additional debugging output (if compiled with DEBUG). -D, --disk Scan for logical volumes on disk(s) instead of getting the information from the kernel. -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about lvscan's activities. --version Prints version number of tool and exits sucessfully. DIAGNOSTICS
lvscan returns an exit code of 0 for success and > 0 for error: 1 no volume groups found 2 invalid volume group name 3 error getting VGDA from kernel 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line SEE ALSO
