Missing and Unable tor Restore/Repair Replica in RAIN6 (Unable to schedule stripes for reconstruction; could not place new replica; replica inconsistency repair failed and No space left on device)

Dear EOS Expert and Administrator,

Three days ago we restart Kolkata:EOS2 after migrated to Quarkdb from Memory-NS.

At first we found that there were permission error in xrdlog.mgm on Master and Slave. We was able read file from EOS , but unable to write. Before migration, we had able read and write also.

Today, we had enable “eos fsck” and then check the xrdlog.mgm log; and found that there are many replication error i.e. “could not place new replica” and “[3009] Unable to schedule stripes for reconstruction”.

We had check the group ls and seem that 4 group balancing were going on. Also check “Unable to schedule stripes for reconstruction” on xrdlog.mgm log for deep investigation.

On above output of eos file info, two replica i.e. eos06 and eos09 are missing. But when we check those mount point i.e. xdata13 in “eos fs ls”, it’s had exist.

[root@eos-mgm ~]# eos -b fs ls | grep xdata13 (It’s exist also in FST)

However the the space occupied on xdata13 by different FST are not same.

So, kindly suggest what to do . How to repair those missing and faulty replicas with safeguard?

Hi Prasun,

Make sure that the EOS instance is update to 4.8.46 before enabling fsck repair for the RAIN layout files. There were some important fixes added in the latest release concerning fsck and RAIN files.

Having said that, it looks that you have groups of 7 file systems and you use RAIN with 7 stripes so there is no extra file systems that can be used to recover any broken or missing stripes. You should have at least 8 file systems per group or use RAIN layout with 6 stripes and not 7. This is the reason the schedule is not able to place new replicas since your groups are too small.

What you can do as an experiment is to (copy and) convert one such file to RAIN with 6 stripes, delete one of the stripes and run eos fsck repair targeted at this file and see if the repair works for you. But remember you need 4.8.46 everywhere for this to work fine.

Cheers,
Elvin

Dear Elvin,

Sorry for late reply.

As per your suggestion, to use RAIN (raid6) layout of 7 strips with 8 FSTs, we add another fst (i.e. eos11.tier2-kol.res.in ) which has same nos of fs and same size of fs. We had untouched the value of sys.forced.nstripes=“7” inside the eos attr. Also change the value of groupsize from 7 to 8 and the value of groupmod is same i.e. 24. EOS package are updated to EOS 4.8.46 (2020) in all eos systems.

Then the errors i.e. [Missing and Unable tor Restore/Repair Replica in RAIN6 (Unable to schedule stripes for reconstruction; could not place new replica; replica inconsistency repair failed and No space left on device) are not coming like before.

After modification of above changes, we restart the eos. But, we notice that “Balancing” are started on all 16 groups. Earlier its running on 4 groups. In converter.log and xrdlog.mgm, there are multiple error like "[ERROR] Server responded with an error: [3010] Unable to open file " , “Operation not permitted”, ERROR ConversionJob, etc.

When investigate xrdlog,mgm and Converter.log thoroughly, we find that the copy of file from /eos/alicekolkata/grid/* to /eos/alicekolkata/proc/conversion/* by tpc were successfully. But during conversion , open of those files at /eos/alicekolkata/proc/conversion/ are failed and show unable to open and Operation not permitted. Examples of such files are given below:-

===============================
Above output clearly showed that files insides folder /eos/alicekolkata/proc/conversion are unable to open and conversion error.

We also read the suggestion in threads i.e. TPC setup with token authentication - #21 by gbiro and File base manual conversion issue - #9 by ebirngru. Link File base manual conversion issue - #14 by esindril suggested that to remove space policy. Accordingly, we had remove space policy parameter i.e. eos space config default space.policy.[layout, nstripes, checksum, blocksize and blockchecksum]=remove.

Also, the permission of /eos/alicekolkata/proc and /eos/alicekolkata/proc/conversion are
drwxr-xr-x 1 root root 20480 Jul 30 2019 proc
drwxrwx— 1 daemon daemon 0 May 28 19:27 conversion.

But, till conversion is failed with permission error.

So, suggest accordingly.

Hi Prasun,

It is normal that after adding the new node you have the balancing trying to bring all the file system to the same level with respect to how much they are filled. In this particular case, I don’t think you are interested in this balancing activity given the number of file systems that you have per group so you could simply disable the balancing inside groups i.e. eos space config default space.balancer=off.

Concerning the Operation not permitted errors indeed the first step is to remove the space.policy configuration. One other thing is to make sure the daemon user is in the list of sudoers when doing eos vid ls. You can achieve this by doing:
eos vid set membership 2 +sudo

Let me know if this helps.

Cheers,
Elvin

Dear Elvin,

Thank for your suggestion.

I had applied " eos vid set membership 2 +sudo".
Now the output of eos vid ls for sudoer is
[root@eos-mgm ~]# eos vid ls|grep sudoer
sudoer => uids(daemon)
[root@eos-mgm ~]#

Also, disabled the balancer and remove the space policy i.e.
##############
eos space config default space.policy=remove
eos space config default space.policy.conversion=remove
eos space config default space.policy.layout=remove
eos space config default space.policy.blockchecksum=remove
eos space config default space.policy.blocksize=remove
eos space config default space.policy.checksum=remove
eos space config default space.policy.nstripes=remove

We had monitoring the xrdlog.mgm in master and slave. Till now, Errors i.e Operation not permitted are not occurred yet.

I try to copy local file to EOS storage by xrdcp and eoscp; but both failed. However when I try to copy the file inside /eos/alicekolkata/grid/ to /tmp by eoscp, it ok and xrdcp is failed.

Hi Prasun,

For this error:

[root@eos-mgm ~]# /opt/eos/xrootd/bin/xrdcp -d1 /root/anaconda-ks.cfg root://eos-mgm.tier2-kol.res.in//eos/alicekolkata/grid/anaconda1.txt

Run: [ERROR] Server responded with an error: [3006] Unable to create file (O_EXCL) /eos/alicekolkata/grid/anaconda1.txt; File exists (destination)

it looks to me that the file already exists, so you could use the xrdcp -f flag to force an overwrite of the file.

For this error:

[root@eos-mgm ~]# /opt/eos/xrootd/bin/xrdcp -f -d1 root://eos-mgm.tier2-kol.res.in//eos/alicekolkata/grid/5g-test /dev/null

Run: [ERROR] Server responded with an error: [3014] Unable to open file /eos/alicekolkata/grid/5g-test; Network is unreachable (source)

it looks that some of the file systems are not available. Can you post the following info?

eos fileinfo /eos/alicekolkata/grid/5g-test
eos node ls
eos fs ls 

Thanks,
Elvin

================

For first error, as you suggested to use xrdcp -f flag to force an overwrite of the file, I have again run xrdcp with -f and till error are same. Indeed the file anaconda1.txt was not exists in /eos/alicekolkata/grid.

So, now copy file as different filename, i.e. /root/anaconda-ks.cfg to /eos/alicekolkata/grid/anaconda2.txt (anaconda2.txt is not exists in eos). But it fails.
( Output of Error in next message)

So, suggest accordingly.

Prasun

Dear Elvin,

(Continuation mail …)

Error messages during copy file as different filename, i.e. /root/anaconda-ks.cfg to /eos/alicekolkata/grid/anaconda2.txt (anaconda2.txt is not exists in eos)

Hi Prasun,

Are you sure your FSTs are reachable on port 1095? By the looks for this trace the client can not connect to any of the FST nodes. Do you have any errors, or as a matter of fact any activity, in the FST logs?

Thanks,
Elvin

Dear Elvin,

I had check the port 1095 on every fst. Interesting it’s work on IPv6. In IPv4, it not listening. See below some output:- (On our EOS system, we only use IPv4.)

All the fst’s are mostly similar error in xrdlog.fst.

Has eos version “EOS 4.8.46 (2020)” support dual stack network?

So, Suggest accordingly.
Prasun

Hi Prasun,

The daemon is listening on both interfaces, the output from netstat is a bit misleading.
Can you paste the output of the following command ran on both the MGM machine and one of the FSTs?

rpm -qa | grep "eos\|xrootd"

Thanks,
Elvin

Hi Prasun,

Can you attach the logs of a write transfer to EOS with xrdcp with flag -d 3?

Thanks,
Elvin

Dear Elvin,

I’ve collected the logs and put it on cernbox. Log contents are unable to fit here due to limitation of characters.

[CERNBox]

Suggest.

Prasun

Hi Prasun,
Elvin is having his deserved vacations, I had a look at your log output.

Can you run this command from your client machine:

env XRD_LOGLEVEL=Dump xrdfs eos05.tier2-kol.res.in:1095 stat /

In the copy log, you essentially get a socket error for the open requests towards the FSTs on port 1095.

You are sure, there is no firewall on FSTs for ipv4/6?

Dear Andreas,

Wishes Elvin to happy vacation.

Firewalld and selinux are stopped in all FSTs and MGM nodes.

The output of “env XRD_LOGLEVEL=Dump xrdfs eos05.tier2-kol.res.in:1095 stat /” are below:

Any chance, that you can add my public key to your MGM and let me log-in there?

It is too difficult to debug this via the forum …

Dear Andreas,

Your public key is added to “eos-mgm.tier2-kol.res.in” (MASTER and Member of QDB) and “eos-qdb.tier2-kol.res.in” (Member of QDB).
Alias name of eos-mgm.tier2-kol.res.in and eos-slave.tier2-kol.res.in are eoskolkata.tier2-kol.res.in.

Let me know that have you able to login those machines?

Regards
Prasun

Perfect, I am in!
