| GemFire XD Reference / gfxd Launcher Commands | |
Display the disk store metadata for a specified disk store directory.
gfxd show-disk-store-metadata <disk-store> <directory>+ [-mcast-port=<port>] [-mcast-address=<address>] [-locators=<addresses>] [-bind-address=<address>] [-<prop-name>=<prop-value>]*
The table describes options and arguments for gfxd show-disk-store-metadata. If no multicast or locator options are specified on the command-line, the command uses the gemfirexd.properties file (if available) to determine the distributed system to which it should connect.
| Option | Description |
|---|---|
| <disk-store> | (Required.) Specifies the name of a disk store for which you want to display metadata. The disk store must be offline. |
| <directory> | (Required.) Specifies one or more disk store file directories. |
| -mcast-port |
Multicast port used to communicate with other members of the distributed system. If zero, multicast is not used for member discovery (specify -locators instead). Valid values are in the range 0–65535, with a default value of 10334. |
| -mcast-address |
Multicast address used to discover other members of the distributed system. This value is used only if the -locators option is not specified. The default multicast address is 239.192.81.1. |
| -locators |
List of locators used to discover members of the distributed system. Supply all locators as comma-separated host:port values. |
| -bind-address | The address to which this peer binds for receiving peer-to-peer messages. By default gfxd uses the hostname, or localhost if the hostname points to a local loopback address. |
| -prop-name |
Any other GemFire XD distributed system property. |
This command displays metadata information for all available disk stores in the specified directory. On Linux RPM installations, the disk store directory and files are owned by the non-interactive gemfirexd user. You must use sudo -u gemfirexd to execute the disk store command.
This command displays metadata for all disk stores in a single directory:
