jrb files filled with Zero's

onmstester onmstester
Recently some of snmp graphs could not be viewed. I've opened the jrb file with jrobin-inspector and it says that the file does not have a header like
jrb files. The file has a size of 200kb like other (usable) jrbs but Using a hex editor revealed that all of its bytes including the file header are all Zero's!
Unfortunately i have no backup of my data, and I've lost it all.
How can i find out what's been corrupting jrb files? could it be a hardware problem (i've been using a 6 * SSD RAID 1+0) ?
How can i find out which rrd files have been corrupted (there are thousands of them) and delete them to be recreated?
I'm using opennms 16 on centos 6.6.

Thanks in advance

Re: jrb files filled with Zero's

Seibold, Michael-2

 

Ø  How can i find out what's been corrupting jrb files?

 

I would look for one of the rrd utilities, by example to export rrd data, and check if they return some usable error code when they open a corrupted file.

 

Ø  could it be a hardware problem (i've been using a 6 * SSD RAID 1+0) ?

 

In about ten years of using different opennms versions on different *x-systems I never observed this problem, even with "classical" disks when they had block errors. So yes, it might be some hardware error, but I really don't know.
