PANIC: lib/../include/dlist.h: _dl_first: 828: !(list->count != 0)

Cause

Dell Technologies har identificeret en kodefejl i cloud-dataflytningsfunktionen, hvilket resulterer i DDFS-genstart enten med ovenstående SEGFAULT- eller PANIC-fejl.

Jira-reference er DDOSCFD-9678

Resolution

For at undgå, at DDFS genstarter under dataflytning på cloud-niveau, skal du overveje at opgradere til DDOS 7.7.1.10 eller nyere, 7.7.2.0.10 eller nyere, 7.8.0.20 eller nyere

Trin:

1. Stop cloud-dataflytningsprocessen # dataflytning stop # dataflytningsstatus              2. Genstart filsystem               # filesys genstart     3. Sørg for, at filsystemet er aktiveret               #filesys status              4. Opgrader systemet til DDOS 7.7.1.10 eller nyere, 7.7.2.0.10 eller nyere, 7.8.0.20 eller nyere.
5. Start cloud-dataflytningsproces               # dataflytning
