In which cases can the "mon_osd_full_ratio" and the "mon_osd_backfillfull_ratio" be exceeded ?

by Raphael Laguerre

Hello, In which cases can the "mon_osd_full_ratio" and the "mon_osd_backfillfull_ratio" be exceeded ? More specifically, in case a subset of OSDs fail, if there isn't any more space left in the remaining OSDs to migrate the PGs of the failed OSDs without exceeding either the "mon_osd_full_ratio" or the "mon_osd_backfillfull_ratio of at least one OSD, how will the cluster behave ? Will it exceed the "mon_osd_full_ratio" or the "mon_osd_backfillfull_ratio" of one or more OSDs to ensure an "active+clean" state ? Best regards, Raphaël

How to properly remove of cluster_network

by Jan Marek

Hello, I would like to remove cluster_network, because I'm using for in 10Gbps adapters, but for public_network I have two 25Gbps adapters in LAG group... I have cluster with orchestrator. # ceph config dump ... global advanced cluster_network 172.30.0.0/16 global advanced public_network a.b.7.0/24 mon advanced public_network a.b.7.0/24 ... How to do it safely? Will be correct to only set: ceph config set global cluster_network a.b.7.0/24 ? Have I then restart mon processes and osd processes? Many thanks for advices.

How to use STS Lite correctly?

Hi, I have a Ceph cluster v16.2.10 To use STS lite, my configures are like the following: ceph.conf ...

Re: S3website range requests - possible issue

by Ondřej Kukla

I was checking the tracker again and I found already fixed issue that seems to be connected with this issue. https://tracker.ceph.com/issues/44508 Here is the PR that fixes it https://github.com/ceph/ceph/pull/33807 What I’m still not understanding is why this is only happening when using s3website api. Is there someone who could shed some light on this? Regards, Ondrej

millions of hex 80 0_0000 omap keys in single index shard for single bucket

by Christopher Durham

I am using ceph 17.2.6 on Rocky 8. I have a system that started giving me large omap object warnings. I tracked this down to a specific index shard for a single s3 bucket. rados -p <indexpool> listomapkeys .dir.<zoneid>.bucketid.nn.shardid shows over 3 million keys for that shard. There are only about 2 million objects in the entire bucket according to a listing of the bucket and radosgw-admin bucket stats --bucket bucketname. No other shard has anywhere near this many index objects. Perhaps it should be noted that this shard is the highest numbered shard for this bucket. For a bucket with 16 shards, this is shard 15. If I look at the list of omapkeys generated, there are *many* beginning with "<80>0_0000", almost the entire set of the three + million keys in the shard. These are index objects in the so-called 'ugly' namespace. The rest ofthey omapkeys appear to be normal. The 0_0000 after the <80> indicates some sort of 'bucket log index' according to src/cls/rgw/cls_rgw.cc. However, using some sed magic previously discussed here, I ran: rados -p <indexpool> getomapval .dir.<zoneid>.bucketid.nn.shardid --omap-key-file /tmp/key.txt Where /tmp/key.txt contains only the funny <80>0_0000 key name without a newline The output of this shows, in a hex dump, the object name to which the index refers, which was at one time a valid object. However, that object no longer exists in the bucket, and based on expiration policy, was previously deleted. Let's say, in the hex dump, that the object was: foo/bar/baz/object1.bin The prefix foo/bar/baz/ used to have 32 objects, say foo/bar/baz/{object1.bin, object2.bin, ... } An s3api listing shows that those objects no longer exist (and that is OK, as they were previously deleted). BUT, now, there is a weirdo object left in the bucket: foo/bar/baz/ <- with the slash at the end, and it is an object not a PRE (fix). All objects under foo/ have a 3 day lifecycle expiration. If I wait(at most) 3 days, the weirdo object with '/' at the end will be deleted, or I can delete it manually using aws s3api. But either way, the log index objects, <80>0_0000.... remain. The bucket in question is heavily used. But with over 3 million of these <80>0_0000 objects (and growing) in a single shard, I am currently at a loss as to what to do or how to stop this from occuring. I've poked around at a few other buckets, and I found a few others that have this problem, but not enoughto cause a large omap warning. (A few hundred <80>0_000.... index objects in a shard), no where near enoughto cause the large omap warning that led me to this post. Any ideas?

multiple rgw instances with same cephx key

by Boris Behrens

Hi, is it possible to use one cephx key for multiple parallel running RGW? Maybe I could just use the same 'name' and the same key for all of the RGW instances? I plan to start RGWs all over the place in container and let BGP handle the traffic. But I don't know how to create on demand keys, that get removed when the RGW shuts down. I don't want to use the orchestrator for this, because I would need to add all the compute nodes to it and there might be other processes in place that add FW rules in our provisioning. Cheers Boris

But at some point, the next snapid will restart at 1? So maybe not the best idea. I could select by date/time but I don't have an easy way to convert the text string to an timestamp... I've looked in the rbd help snap ls, there seem to be now way to sort, format the output of the timestamp,... Any advice will be appreciated. Greetings, Dominique.

RGW External IAM Authorization

by Seena Fallah

Hi Community, I recently proposed a new authorization mechanism for RGW that can let the RGW daemon ask an external service to authorize a request based on AWS S3 IAM tags (that means the external service would receive the same env as an IAM policy doc would have to evaluate the policy). You can find the documentation of the implementation here: https://github.com/clwluvw/ceph/blob/rgw-external-iam/doc/radosgw/external-… And the PR here: https://github.com/ceph/ceph/pull/53345 We would love to hear feedback if anyone else feels this would be a need for them and what you would think about the APIs. Best,

Recently started OSD crashes (or messages thereof)

by Luke Hall

Hi, Since the recent update to 16.2.14-1~bpo11+1 on Debian Bullseye I've started seeing OSD crashes being registered almost daily across all six physical machines (6xOSD disks per machine). There's a --block-db for each osd on a LV from an NVMe. If anyone has any idea what might be causing these I'd appreciate some insight. Happy to provide any other info which might be useful. Thanks, Luke { "assert_condition": "cur2 >= p.length", "assert_file": "./src/os/bluestore/BlueStore.h", "assert_func": "virtual void RocksDBBlueFSVolumeSelector::sub_usage(void*, const bluefs_fnode_t&)", "assert_line": 3875, "assert_msg": "./src/os/bluestore/BlueStore.h: In function 'virtual void RocksDBBlueFSVolumeSelector::sub_usage(void*, const bluefs_fnode_t&)' thread 7f7f54f25700 time 2023-09-20T14:24:00.455721+0100\n./src/os/bluestore/BlueStore.h: 3875: FAILED ceph_assert(cur2 >= p.length)\n", "assert_thread_name": "bstore_kv_sync", "backtrace": [ "/lib/x86_64-linux-gnu/libpthread.so.0(+0x13140) [0x7f7f68632140]", "gsignal()", "abort()", "(ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x16e) [0x55b22a49b5fa]", "/usr/bin/ceph-osd(+0xac673b) [0x55b22a49b73b]", "(RocksDBBlueFSVolumeSelector::sub_usage(void*, bluefs_fnode_t const&)+0x11e) [0x55b22ab0077e]", "(BlueFS::_flush_range_F(BlueFS::FileWriter*, unsigned long, unsigned long)+0x5bd) [0x55b22ab9b8ed]", "(BlueFS::_flush_F(BlueFS::FileWriter*, bool, bool*)+0x9a) [0x55b22ab9bd7a]", "(BlueFS::fsync(BlueFS::FileWriter*)+0x79) [0x55b22aba97a9]", "(BlueRocksWritableFile::Sync()+0x15) [0x55b22abbf405]", "(rocksdb::LegacyWritableFileWrapper::Sync(rocksdb::IOOptions const&, rocksdb::IODebugContext*)+0x3f) [0x55b22b0914d1]", "(rocksdb::WritableFileWriter::SyncInternal(bool)+0x1f4) [0x55b22b26b7c6]", "(rocksdb::WritableFileWriter::Sync(bool)+0x18c) [0x55b22b26b1f8]", "(rocksdb::DBImpl::WriteToWAL(rocksdb::WriteThread::WriteGroup const&, rocksdb::log::Writer*, unsigned long*, bool, bool, unsigned long)+0x366) [0x55b22b0e4a98]", "(rocksdb::DBImpl::WriteImpl(rocksdb::WriteOptions const&, rocksdb::WriteBatch*, rocksdb::WriteCallback*, unsigned long*, unsigned long, bool, unsigned long*, unsigned long, rocksdb::PreReleaseCallback*)+0x12cc) [0x55b22b0e0c5a]", "(rocksdb::DBImpl::Write(rocksdb::WriteOptions const&, rocksdb::WriteBatch*)+0x4a) [0x55b22b0df92a]", "(RocksDBStore::submit_common(rocksdb::WriteOptions&, std::shared_ptr<KeyValueDB::TransactionImpl>)+0x82) [0x55b22b036c42]", "(RocksDBStore::submit_transaction_sync(std::shared_ptr<KeyValueDB::TransactionImpl>)+0x96) [0x55b22b037cc6]", "(BlueStore::_kv_sync_thread()+0x1201) [0x55b22aafc891]", "(BlueStore::KVSyncThread::entry()+0xd) [0x55b22ab2792d]", "/lib/x86_64-linux-gnu/libpthread.so.0(+0x7ea7) [0x7f7f68626ea7]", "clone()" ], "ceph_version": "16.2.14", "crash_id": "2023-09-20T13:24:00.562318Z_beb5c664-9ffb-4a4e-8c61-166865fd4e0b", "entity_name": "osd.8", "os_id": "11", "os_name": "Debian GNU/Linux 11 (bullseye)", "os_version": "11 (bullseye)", "os_version_id": "11", "process_name": "ceph-osd", "stack_sig": "90d1fb6954f0f5b1e98659a93a1b9ce5a5a42cd5e0b2990a65dc336567adcb26", "timestamp": "2023-09-20T13:24:00.562318Z", "utsname_hostname": "cphosd02", "utsname_machine": "x86_64", "utsname_release": "5.10.0-23-amd64", "utsname_sysname": "Linux", "utsname_version": "#1 SMP Debian 5.10.179-1 (2023-05-12)" } -- All postal correspondence to: The Positive Internet Company, 24 Ganton Street, London.
