Description

This tool is designed to help track down a specific resource in depots without the ability to control a drive’s status LED. This is accomplished by generating activity on the requested drive or all drives except the one given. Output is printed to stdout after every gigabyte is transferred showing the transfer rate and time. The test can be stopped by pressing the <ENTER> key at any time.

Options

-d

Enable minimal debug output

-dd

Enable FULL debug output

-network_chksum type blocksize

Enable network checksumming for transfers. type should be SHA256, SHA512, SHA1, or MD5. blocksize determines how many bytes to send between checksums in kbytes.

-disk_chksum type blocksize

Use block level checksum allocations. type should be NONE, SHA256, SHA512, SHA1, or MD5. If NONE is specified it will force the creation of allocations without checksums. If the option is not specified then the resources default options are used. blocksize determines how many bytes to send between checksums in kbytes.

-config ibp.cfg

Use the IBP configuration defined in given file. nthreads overrides value in config file unless -1.

-phoebus ppath

Use Phoebus protocol for data transfers. The Phoebus path si a comma separated List of phoebus hosts/ports, eg. gateway1/1234,gateway2/4321.

-tcpsize tcpbufsize

Use this value, in KB, for the TCP send/recv buffer sizes.

-duration duration

Allocation duration in sec. Needs to be big enough to last the entire run. The default duration is 900 sec.

-skip

Hit all drives on the depot except the resource given

-auto

Automatically configure nthreads, ibp_timeout, q_len, n_alloc, alloc_size, and block_Size

depot port RID

Depot tuple comprised of the depot hostname, port and resource to use. A RID of 0 lets the depot pick a resource.

nthreads

Max Number of simultaneous threads to use. Use -1 for defaults or value in ibp.cfg

ibp_timeout

Timeout(sec) for each IBP copmmand

q_len

Number of commands queued at any time. Controls how long it takes to stop.

n_alloc

Number of allocations to use

alloc_size

Size of each allocation in KB for sequential and random tests

block_size

Size of each write operation in KB for sequential and random tests
