Hello everybody,
I have some questions about the PVFS_SERV_GETCONFIG request in the
client side. When I trace the msgpairs state machine, I can
see the operations using this sm (when i post an I/O operation and a
new file should be created):
- PVFS_SERV_GETCONFIG
- PVFS_SERV_LOOKUP_PATH
- PVFS_SERV_GETATTR
- PVFS_SERV_CREATE (one for a metafile and severals for datafiles)
- PVFS_SERV_SETATTR
- PVFS_SERV_CRDIRENT
Searching in the PVFS code, I found that the PVFS_SERV_GETCONFIG
request is filled in the “server-get-config.sm” state machine.
My questions are:
1.- What kind of information is fetched from the server in the
client-side in this request?
2.- Is it necessary get that information of each server, both meta and
data servers?
3.- I understand that servers configuration is cached in the client
side when they are initialized, is it right?
4 .- And last, can a particular server configuration be different to
another conf. server?
My system configuration is:
- One metadata server
- Five I/O servers
- One client accesing to system
Thanks in advance,
Erik
