[Gluster-devel] Suggested statedump sample strings for Bug 915629 (Improve debuggability of inode/entry locks)

[Anuradha Talur]

Hi all,

The sample strings related to FOP to be printed in statedump to improve the debuggability of inode/entrylks are :

Sample statedump for WRITE is as follows:

inodelk.inodelk[0](ACTIVE)=type=WRITE, fop=WRITE, from offset=some-offset, for len-of-data=some-len, whence=0, start=0, len=0, pid = 0, owner=9c7fb90100000000, transport=0x221ef70, connection-id=atalur-4117-2013/09/12-06:30:12:765987-apv-client-0-0, granted at Thu Sep 12 12:02:06 2013

The FOPs and corresponding info that will be added to their statedump are given below.

1) "FALLOCATE | DISCARD" : FOP , len and offset 

2) "CREATE | MKNOD | MKDIR" : FOP, loc and mode?

3) "RMDIR | UNLINK" : FOP and loc

4) "LINK | SYMLINK | RENAME" : FOP , newloc and oldloc

5) "TRUNCATE | WRITEV" : FOP, offset and length_of_data

6) " FSETATTR | SETATTR" : FOP, loc, last_access_time and last_modification_time

7) "REMOVEXATTR" : FOP, name and loc

8) "SETXATTR" : FOP and loc

9) "FSETXATTR" : FOP and flags?

Please let me know if any other information is required along with these.

Regards,
Anuradha.
