I'm happy to announce the another release of the go-ceph API
bindings. This is a regular release following our every-two-months release
cadence.
https://github.com/ceph/go-ceph/releases/tag/v0.4.0
The bindings aim to play a similar role to the "pybind" python bindings in the
ceph tree but for the Go language. These API bindings require the use of cgo.
There are already a few consumers of this library in the wild and the
ceph-csi project is starting to make use of this library.
Specific questions, comments, bugs etc are best directed at our github issues
tracker.

Hi all,
I have a question regarding following rules in Ceph CRUSH map:
enum crush_opcodes {
/*! do nothing
*/
CRUSH_RULE_NOOP = 0,
CRUSH_RULE_TAKE = 1, /* arg1 = value to start with */
CRUSH_RULE_CHOOSE_FIRSTN = 2, /* arg1 = num items to pick */
/* arg2 = type */
CRUSH_RULE_CHOOSE_INDEP = 3, /* same */
CRUSH_RULE_EMIT = 4, /* no args */
CRUSH_RULE_CHOOSELEAF_FIRSTN = 6,
CRUSH_RULE_CHOOSELEAF_INDEP = 7,
CRUSH_RULE_SET_CHOOSE_TRIES = 8, /* override choose_total_tries */
CRUSH_RULE_SET_CHOOSELEAF_TRIES = 9, /* override chooseleaf_descend_once */
CRUSH_RULE_SET_CHOOSE_LOCAL_TRIES = 10,
CRUSH_RULE_SET_CHOOSE_LOCAL_FALLBACK_TRIES = 11,
CRUSH_RULE_SET_CHOOSELEAF_VARY_R = 12,
CRUSH_RULE_SET_CHOOSELEAF_STABLE = 13
};
Can we skip specific rules ? Or lets say, what are the minimum number of
rules required by CRUSH?
Because my understanding is, it all depends on map hierarchy. If we have a
particular/given hierarchy, we can skip certain rules?
Hello all,

I have a 3 host storage cluster with 10 osd on each host. the other day 5 drives on a single host went down and the other 5 failed to come up after reboot.
In my attempts to understand the cause of the issue I realize that I need some guidance to diagnose the problem.
I have tried ceph-disk activate-all and get the following errors:
[root@faraday ~]# ceph-disk activate-all
mount_activate: Failed to activate

any ideas what would cause this?

Hi all,
I have a question regarding a function called *crush_choose_firstn* in Ceph
source code namely *mapper.c* This function has following pointer
variables :
- const struct crush_map *map,
- struct crush_work *work, const struct crush_bucket *bucket,
- int *out,
- const __u32 *weight,
- int *out2,
- const struct crush_choose_arg *choose_args
*- const struct crush_map *map.*
What is the maximum size of data involved here? I mean what is the upper
bound?

Bobby
