Referring to FIG. 1, Fig. 1 is a kind of flow chart of file access method in the embodiment of the present invention, this method includes following
Step:
S101, the file access request that target ganesha is sent is received, and determines the file destination requested access to and visit
Ask operation.
When the mds in distributed file system receives the file access request of target ganesha transmission, it is first determined
The file destination and access operation requested access to out.Wherein, access operation includes but is not limited to buffer write operation, read buffer
Operation and checks operation at delete operation, and access operation can be divided into exclusive access type and share and access class according to whether monopolizing
Type, exclusive access type include buffering write operation (writing buffer), read buffer operation (reading cache), delete operation, share and access
Type includes caching permission.
S102, when access operation belongs to exclusive access type, judge whether target ganesha monopolizes.
When access operation belongs to exclusive access type, such as access operation is that when reading cache or writing buffer, then can sentence
Whether disconnected target ganesha monopolizes.Specifically, whether can be assigned by judging the access authority of the exclusive form of file destination
Mode, determine whether target ganesha monopolizes.Specifically, being exclusive if unallocated, if having distributed non-exclusive.It is preferred that
This document access request can be then inserted into and wait when the access authority of the exclusive type of hard objectives file has been assigned by ground
Queue avoids the occurrence of file access request without response to distribute to target ganesha in time after recycling access authority
The case where.
If the determination result is YES, then the operation of step S103 can be performed.
S103, access authority is distributed to target ganesha, so that target ganesha accesses to file destination.
Wherein, access authority includes read and write access permission, buffer permission and cache permission.
It, at this time can be by read and write access permission, buffer permission and cache permission when hard objectives ganesha is exclusive
Distribute to target ganesha.Target ganesha is allowed to access in exclusive form to file destination.Target ganesha
After obtaining read and write access permission, buffer permission and cache permission, exclusive access can be carried out to file destination.
Preferably, when accessing to file destination, specific access process includes:
Step 1: target ganesha judges whether to have cached file destination；
Step 2: if it is, directly executing access operation to the file destination in caching；
Step 3: if it is not, then obtain file destination from meta data server, and after obtaining file destination, it is right
File destination executes access operation.
It is illustrated for ease of description, below combining above three step.
For accelerate response speed, can in target ganesha caching of target file, when needing access target file, then
The interaction time-consuming that file destination is obtained from mds can be reduced by way of judging whether caching of target file.Specifically, working as
When target ganesha has cached file destination, then access operation directly is executed to the file destination in caching, such as to file destination
It carries out writing buffer.When the uncached file destination of target ganesha, then need first got from mds file destination and then
It accesses operation to file destination.
S104, after access specify duration in without read-write operation when, to target ganesha sending permission recycle message, and
Revocation of access limit.
