NAME
gvfs - GIO virtual file system DESCRIPTION
GIO provides a VFS API to GLib applications. It includes a 'local' implementation using POSIX. gvfs provides implementations that go beyond that and allow to access files and storage using many protocols, such as ftp, http, sftp, dav, obexftp, etc. It also provides support for trash folders, for cd burning and for monitoring interesting devices and volumes on the computer. Applications use gvfs indirectly, by means of GIO loading the gvfs module that implements the GIO extension points. The gvfs support for volume monitoring is included in a separate loadable module. The actual gvfs implementation is distributed over a number of processes. None of these are expected to be started from the commandline, except for debugging purposes. Main processes: o gvfsd - the main gvfs daemon o gvfs-fuse-daemon - mounts gvfs as a fuse filesystem o gvfsd-metadata - writes gvfs metadata Volume monitors: o gvfs-udisks2-volume-monitor - a udisks-based volume monitor o gvfs-afc-volume-monitor - a volume monitor for Apple iPhone/iPod Touch devices Mount backends: o gvfsd-afc - mounts iPhone/iPod touch volumes o gvfsd-afp - mounts Apple Filing Protocol volumes o gvfsd-afp-browse - browses Apple Filing Protocol volumes o gvfsd-archive - mounts archive files in various formats o gvfsd-burn - provides a location for burning CDs o gvfsd-cdda - mounts audio CDs o gvfsd-computer - provides computer:// o gvfsd-dav - mounts DAV filesystems o gvfsd-dnssd - browses dnssd o gvfsd-ftp - mounts over FTP o gvfsd-http - mounts over HTTP o gvfsd-localtest - a test backend o gvfsd-network - provides network:// o gvfsd-obexftp - mounts over obexftp o gvfsd-recent - provides recent:// o gvfsd-sftp - mounts over sftp o gvfsd-smb - mounts Windows Shares Filesystem volumes o gvfsd-smb-browse - browses Windows Shares Filesystem volumes o gvfsd-trash - provides trash:// ENVIRONMENT
GIO_USE_VFS If set, specifies the GIO vfs implementation to use. Possible values include 'local' and 'gvfs'. GIO_USE_VOLUME_MONITOR If set, specifies the GIO volume monitor implementation to use. Possible values include 'unix', 'GProxyVolumeMonitorUDisks2', as well as other native volume monitors that are described in the key files in $XDG_DATA_DIRS/gvfs/remote-volume-monitors. FILES
$XDG_DATA_DIRS/gvfs/mounts This directory contains key files describing mount daemons. $XDG_DATA_DIRS/gvfs/remote-volume-monitors This directory contains key files describing remote volume monitors. SEE ALSO

NAME
cmvxserviced - monitor VxVM and CVM volumes for a high availability package. SYNOPSIS
cmvxserviced [-h|-v] [-O log_file] [-D log_level] [-t poll_interval] volume_path... DESCRIPTION
cmvxserviced monitors VxVM and CVM volumes. It runs as a service within a package that depends on the monitored storage. When a monitored volume fails or becomes inaccessible (see Scope of Monitoring), the service will exit, causing the package to fail on the current node. The package's failover behavior depends on its configured settings. cmvxserviced periodically probes each volume named by volume_path, which must identify a block device file. Scope of Monitoring The VxVM Volume Monitor detects the following failures: o Failure of the last link to a storage device or set of devices critical to volume operation o Failure of a storage device or set of devices critical to volume operation o An unexpected detachment or disablement of a volume The VxVM Volume Monitor does not detect the following failures: o Failure of a redundant link to a storage device or set of devices if a functioning link remains o Failure of a mirrored plex within a volume (assuming at least one plex is functional) o Corruption of data on a volume which VxVM or CVM regards as enabled and active Options cmvxserviced supports the following options: -h Displays the usage, as listed above, and exits. -v Displays the monitor version and exits. NOTE Do not include the -h or -v parameters in your service command; this will result in immediate package failure at runtime. -O log_file Specifies a file for logging (log messages are printed to the console by default). -D log_level Specifies the log level. The level of detail logged is directly proportional to the numerical value of the log level. That is, a log level of 7 will provide the greatest amount of log information. The default log level is 0. -t poll_interval Specifies the interval between volume probes. You can specify a polling interval of as little as 1 (one second), but bear in mind that a short polling interval (less than 10 seconds) may impair system performance if you are monitoring a large number of volumes. HP recom- mends a polling interval of at least 10 seconds if 50 or more volumes are being monitored by a single service com- mand. The default polling interval is 60 seconds. EXAMPLES
/usr/sbin/cmvxserviced -O /pkg1/monlog.log -D 3 /dev/vx/dsk/cvm_dg0/lvol2 This command monitors a single volume, /dev/vx/dsk/cvm_dg0/lvol2, at log level 3, with a polling interval of 60 seconds, and prints all log messages to the file /pkg1/monlog.log. There should be a one to one relationship between monitoring services and log files. This provides a means to correlate log messages with the originating monitor. /usr/sbin/cmvxserviced /dev/vx/dsk/cvm_dg0/lvol1 dev/vx/dsk/cvm_dg0/lvol2 This command monitors two volumes at the default log level of 0, with a polling interval of 60 seconds, and prints all log messages to the console. /usr/sbin/cmvxserviced -t 10 /dev/vx/dsk/cvm_dg2/lvol3 This command monitors a single volume at log level 0, with a polling interval of 10 seconds, and prints all log messages to the console.
