A cosmetical issue but I've been wondering about it as long as I can
remember, so at the risk of appearing as a complete fool ...
If a single buffer buf in a sequential metacycbuf is filled there's a
message in the syslog like
| Dec  7 00:23:38 emmer innd: CNFS-sm: metacycbuff ALL cycbuff is moved
|                                                     to 18_04 remain calm

However, examination with cnfsstat reveals that 18_04 is the old buffer
which is now full, and writing continues now into another one (18_05 in
my case). So the message should read rather like "moved from 18_04" or
probably "moved to 18_05".

Now looking at the sources:

|   if (!SMpreopen) CNFSshutdowncycbuff(cycbuff);
|   syslog(L_NOTICE, "%s: metacycbuff %s cycbuff is moved to %s remain calm",
|        LocalLogName, metacycbuff->name, cycbuff->name);

cycbuff appearently still points to the old buffer.

|   metacycbuff->memb_next = (metacycbuff->memb_next + 1) % metacycbuff->count;
|   cycbuff = metacycbuff->members[metacycbuff->memb_next];  

Now finally the new one.

|   if (!SMpreopen && !CNFSinit_disks(cycbuff)) {
(...)
|   }

My suggestion is to put the syslog statement at the place here. Same as
patch in the attachment.
