Hello!
I tested your frep utility on CURRENT. Device code (frep.c.patch) has error:
243+ if (strlen(xpath) > 1) { /* must be - if (strlen(xpath) > 0) */
244+ *cptr++ = '/';
245+ }
When I use dd command to create big file
(dd if=/dev/urandom of=/{path_to_frep_directory}/bigfile bs=1024 count=10000),
frep goes to overrun very quickly :(
Are you have some ideas to correct this problem?
Maybe dynamic queue with sysctl tunable size will help?
And one more question:
What about data recovery? How directory data from client will get to new
server? I mean if one server goes down and i'll set up new one instead of it.
Do you have some ideas or protocol?
Best wishes, Evgeny :)
