Description Tzahi Ashkenazi 2020-07-06 09:10:28 UTC

Description of problem:

while running  ovirt-log-collector tool .
its failed on connecting to the PostgreSQL and exit on error 

ERROR: Could not collect PostgreSQL information: [Errno 2] No such file or directory: '/var/tmp/logcollector-_hrqeh5j/working/log-collector-data/sosreport-rhev-red-01-2020-07-06-nhaduce.tar.xz.sha256' -> '/var/tmp/logcollector-_hrqeh5j/working/log-collector-data/postgresql-sosreport-rhev-red-01-2020-07-06-nhaduce.tar.xz.sha256'

Version-Release number of selected component (if applicable):

vdsm-4.40.22-1.el8ev.x86_64
rhv-release-4.4.1-10-001.noarch


How reproducible:
from the engine run the > ovirt-log-collector

Steps to Reproduce:
1. from the engine run the > ovirt-log-collector

Actual results:
INFO: Gathering PostgreSQL the oVirt Engine database and log files from localhost...
ERROR: Could not collect PostgreSQL information: [Errno 2] No such file or directory: '/var/tmp/logcollector-_hrqeh5j/working/log-collector-data/sosreport-rhev-red-01-2020-07-06-nhaduce.tar.xz.sha256' -> '/var/tmp/logcollector-_hrqeh5j/working/log-collector-data/postgresql-sosreport-rhev-red-01-2020-07-06-nhaduce.tar.xz.sha256'


Expected results:
without any errors such as above 

Additional info:
1. tested on rhev 4.3 which working without any errors , seems like its related to the new DB 
2. while running the ovirt-log-collector with the --local-tmp flag in order to redirect the results to another folder other then /tmp  
its still write the results  to /tmp 

example : 
 ovirt-log-collector  --no-hypervisors  --local-tmp=/tzahi_mount_test/log_collector_bug/LOGCOLLECT1/ --log-file=/tzahi_mount_test/log_collector_bug/LOGCOLLECT2/collect.log

INFO: Skipping hypervisor collection...
INFO: Creating compressed archive...
ERROR: tar: /tmp/sosreport-LogCollector-20200706041628.tar: Cannot write: No space left on device
ERROR: tar: Error is not recoverable: exiting now

Comment 1 Douglas Schilling Landgraf 2020-07-07 11:14:52 UTC

Start investigating.

Comment 3 Sandro Bonazzola 2020-07-13 09:46:21 UTC

Moving back to modified since ovirt-log-collector-4.4.2-2 was not included in 4.4.1 compose

Comment 4 Michal Skrivanek 2020-07-23 12:45:59 UTC

doesn't matter if it's in a compose or not if FixedInVersion clearly specifies the package. Fix is available there and QE can either verify with that or wait until a compose exists

Comment 5 Douglas Schilling Landgraf 2020-07-30 23:45:40 UTC

*** Bug 1862169 has been marked as a duplicate of this bug. ***

Comment 6 Sandro Bonazzola 2020-08-04 13:41:15 UTC

As a workaround, you can still collect data from the engine by running sos-report.

Comment 7 Guilherme Santos 2020-08-27 08:52:48 UTC

Verified on:
ovirt-engine-4.4.2.3-0.6.el8ev.noarch
ovirt-log-collector-4.4.3-1.el8ev.noarch

Steps:
1. # fallocate -l $((`df | grep /tmp | awk '{print $4}'` - 100))K /tmp/fake.file
2. # ovirt-log-collector --local-tmp=/root/local_tmp

Results:
No PostgreSQL and tmp files created on dir specified on --local-tmp (no issue with lack on space on /tmp)
