Virtual SAN NIC has been added - explanation, troubleshooting

[SebastianGrugel]

Hi All

Today we found this alert on host in cluster.

Warning:

/bin/hostd crashed (1 time(s) so far) and a core file might have been created at /var/core/hostd-worker-zdump.000. This might have caused connections to the host to be dropped

When that kind of error is appears ? where can we try find more logs for those events ?

Good morning, maybe in /var/log/vsantraces  This command will make them human readable:  zcat vsantraces--2016-05-03T14h10m49s522.gz | /usr/lib/vmware/vsan/bin/vsanTraceReader.py > test.txt

You will need to change the .gz file name to whatever yours is.  Thank you, Zach.

Command works. Thanks

But after this conversion one file have above 600 MB. What you use for opening that big file ?
For NotePad++ file is too big.

You can either split the file up into smaller files or try something like:  Windows Text Editor Free Download  On Windows 10, the default text editor was able to open a 300 MB file.  Thank you, Zach.
