XCP NFS command reference |
The XCP NFS estimate command is used to estimate the time to complete a baseline copy from the source to destination. It calculates the estimated time to complete a baseline copy by using all of the current available system resources, such as CPU, RAM, Network, and other parameters. You can use the -target option to start a sample copy operation and get the estimation time.
xcp estimate -id <name>The following table lists the estimate parameters and their description.
| Parameter | Description |
|---|---|
Specifies the catalog name of a previous copy or scan index. |
|
Uses gigabits of bandwidth to estimate best-case time (default: 1). |
|
Specifies the target to use for live test copy. |
|
Specifies the duration of live test copy (default: 5m). |
|
Specifies the read/write block size (default: 64k). |
|
Specifies the request size for reading directories (default: 64k). |
|
Preserves access time of the file or directory (default: False). |
|
Sets the log level; available levels are INFO, DEBUG (default: INFO) |
Use the -id <name> parameter with the estimate command to exclude the files and directories that match the filter.
xcp estimate -id <name>Use the -gbit <n> parameter with the estimate command to estimate best-case time (default: 1). This option cannot be used with the -target option.
xcp estimate -gbit <n> -id <name>Use the -target <path> parameter with the estimate command to specify target to use for live test copy.
xcp estimate -t 100 -id <name> -target <path>Use the -t <n[s|m|h]> parameter with the estimate command to specify the duration of live test copy. The default value is 5m.
xcp estimate -t <n[s|m|h]> -id <name> -target <path>Use the -bs <n[k]> parameter with the estimate command to specify the read/write block size. The default value is 64k.
xcp estimate -id <name> -bs <n[k]>Use the -dircount <n[k]> parameter with the estimate command to specify the requested size for reading directories. The default value is 64k.
xcp estimate -id <name> -dircount <n[k]> -t <n> -target <path>Use the -parallel <n> parameter with the estimate command to specify the maximum number of concurrent batch processes. The default value is 7.
xcp estimate -loglevel <name> -parallel <n> -id <name>Use the -preserve-atime parameter with the estimate command to preserve the access time of the file or directory. The default value is false.
xcp estimate -loglevel <name> -preserve-atime -id <name>Use the -loglevel <name> parameter with the estimate command to set the log level; available levels are INFO and DEBUG. The default level is INFO.
