gfwhere1

Usage

Overview

The gfwhere command prints hostnames of filesystem nodes which hold replicas of the specified files.

Options

-a

Displays information of all replicas. This is similar to specifying the -dio options.

-d

Displays replicas on filesystem nodes which are currently down as well.

-F

Displays the following indicators just after each hostname. If the replica has been logically removed, but may still remain phisically, ";" and the replica's generation number are displayed. If the replica is incomplete because it's in the midst of replication, "?" is displayed. If the host is currently down, "-" is displayed.

-h host

Only displays files stored on the specified host. When the -h option is specified multiple times, it displays files stored on all specified hosts. When the host A and host B are specified, it displays files stored on both host A and host B. The -h option can be specified up to three times.

-i

Displays incomplete replicas which are in the midst of replication.

-l

Displays in long format as follows.

This displays one hostname in each line.

If -o option or -a option is specified, this displays the generation number of the replica after the hostname.

If -d option or -a option is specified, this displays an indicator which shows whether this host is down (d) or up (-) at next column.

If -i option or -a option is specified, this displays an indicator which shows whether this replica is incomplete (i) or not (-) at next column. In the former case, this replica is in the midst of replication.

If -o option or -a option is specified, this displays an indicator which shows whether this replica is obsolete (o) or not (-) at next column. In the former case, this replica has been logicall removed.

-m N

Only displays files having less than or equal to N replicas and having greater than 0 bytes.

-o

Displays obsolete replicas which has been logically removed, but may still remain phisically.

-r, -R

Displays subdirectories recursively.

-?

Displays a list of command options.
