Backup failed unexpectedly! ERROR

Can you post the contents of the created config file?

Yes, here it is:

[Misc]snapshotName = fullBackup
restorePointLimit = 1

[Database]
dbName = xxxxxx
dbUser = yyyyyy

[Transmission]

[Mapping]
v_xxxxxx_node0001 = 127.0.0.1:/tmp/vbr

If i add the --debug 3 option i can see this error:

Traceback (most recent call last):  File "/opt/vertica/bin/vbr.py", line 2526, in backup
    prepareAll()
  File "/opt/vertica/bin/vbr.py", line 1888, in prepareAll

    concurrency_upperboud = int(subprocess.Popen(['ulimit -u'], shell=True, stdout= subprocess.PIPE).communicate()[0].strip())

backup failed unexpectedly!

Thansk for your help

Is the OS Ubuntu?
Can you provide the output of ls -l /bin/sh

It's Debian,

lrwxrwxrwx 1 root root 4 Dec 17 10:53 /bin/sh -> bash

Can you try running -
ulimit -u

I get "unlimited"

Hi Fredou!


1. Can you post output for:

python -c "import json; print json.dumps('/opt/vertica/bin/validators.sh', indent=2)"

2. Modify limits.conf file, set max number of processes (lets say db super user is dbadmin):

dbadmin  -   nproc  65536

3. Validate settings:

$ ulimit -u
65536

do reboot and try backup.


PS
Try to validate it without reboot, set limit manually and if it do not hangs an error run backup.

*********

How to set limit manually?

ulimit -u 65536

if it do not throws an error so try to do a backup.

Example of error:

daniel@synapse:/etc/security$ ulimit -u 131072
bash: ulimit: max user processes: cannot modify limit: Operation not permitted

Regards, idiot

Thanks, the "ulimit -u 65536" did the trick !

Hi!

I will ask to run a first command from my post above one more time. You have to set a proper value(65536 - is an arbitrary value) for nproc (the key is max_user_proc)
