permission to file

[Roshan]

Centos 7

Dear Erman,

how are you?

I have a question on Linux permission.

Striim is giving error:
WA-100 : Unexpected Exception. Cause: Trying to recovery from file {cbs_cdr_voice_20211102_601_101_161779.add.gz} which is not found

but file is present on disk.

Striim is running as user striim.
[root@RB-BIGD-STRIIM1 archive]# id striim
uid=101(striim) gid=1(bin) groups=1(bin),10(wheel),100(users),1003(other)


source
# ls -ltr /data//CDR/inocs/voice/archive/cbs_cdr_voice_20211102_601_101_161779.a       dd.gz
-rw-r-----   1 inocs    other      36140 Nov  2 17:44 /data//CDR/inocs/voice/arc       hive/cbs_cdr_voice_20211102_601_101_161779.add.gz

target server(striim)
[root@RB-BIGD-STRIIM1 archive]# ls -ltr cbs_cdr_voice_20211102_601_101_161779.add.gz
-rw-r-----+ 1 60075 bin 36140 Nov  2 17:44 cbs_cdr_voice_20211102_601_101_161779.add.gz

Kindly advise why striim fails to recover from this file?

Regards,

Roshan

I am not an expert in Striim, but the file permissions seem so restrictive..
You may try adding some more permissions to the group-related part of the permissions and retry.
Actually, target permissions seem okay.. However; as for the source, you didn't send me the output of the "id striim" command, so there may be some lack in the permissions.. In source, you have "other" for the group ownership, so check an eye on that.

Also check the permission of the file residing in the same directory.. The ones that Striim was able to use for doing the recovery, so compare them.. If everything (in terms of permission) seem identical, then you may have another problem, and that error may just be misleading.. So we got to check these as a whole.

Hi Erman,

thanks for the update.

the id for user striim I sent you is on target(striim server).

[root@RB-BIGD-STRIIM1 archive]# id striim
uid=101(striim) gid=1(bin) groups=1(bin),10(wheel),100(users),1003(other)

target server(striim)
[root@RB-BIGD-STRIIM1 archive]# ls -ltr cbs_cdr_voice_20211102_601_101_161779.add.gz
-rw-r-----+ 1 60075 bin 36140 Nov  2 17:44 cbs_cdr_voice_20211102_601_101_161779.add.gz

source
# ls -ltr /data//CDR/inocs/voice/archive/cbs_cdr_voice_20211102_601_101_161779.a       dd.gz
-rw-r-----   1 inocs    other      36140 Nov  2 17:44 /data//CDR/inocs/voice/arc       hive/cbs_cdr_voice_20211102_601_101_161779.add.gz

Can you please advise how to add more permissions to the group related part?

[Roshan]

source does not have user striim.

I check the directory permissions. Files are actually located in the archive directory e.g
/data/CDR/inocs/voice/archive

drwxrwxr-x. 22 60075   101    34 Nov  6 19:04 inocs
drwxr-xr-x+ 59  60093 bin             67 Nov 11 10:12 CDR
drwxrwxrwx.  6 60075  101       42 Nov 12 07:05 voice
drwxrwxrwx. 2 60075  101   396701 Nov 12 07:03 archive

user striim does not have group 101.

I noticed on source permission is
-rwxrwxrwx   1 inocs    other      32816 Nov  2 17:00 archive/cbs_cdr_voice_20211102_601_101_161251.add.gz

while on target:
-bash-4.2$ ls -ltr archive/cbs_cdr_voice_20211102_601_101_161251.add.gz
-rwxrwxrwx. 1 60075 bin 32816 Nov  2 17:00 archive/cbs_cdr_voice_20211102_601_101_161251.add.gz

Roshan, the outputs you provided doesn't help.
Please use the OS user that Striim uses to do its work and try to read those .gz files..(with zcat or something.. Dont unzip/extract them, just tryo to read their contents) If you can read them by going into the directory where they reside with the relevant OS user, then it means Striim should be able to read them and the problem is somewhere:) But if you can't read them, then we will modify the permissions..

In the mean time, if you have a direct question (related to OS user/group permissions) for me, please ask.

[Roshan]

Hi,

yes, Striim os user is able to read the files (gz).

[ErmanArslansOracleBlog]

Can it read the file both on source and target?
