And here is an error when I attempted to start a database with datafile in ASM
ORA-15025: could not open disk "/dev/sdd1"
ORA-27041: unable to open file
Linux-x86_64 Error: 13: Permission denied
On a diffent server oracle linux 7.9 with kernel 5.4.17-2011.6.2.el7uek.x86_64 : I don't have this permission denied.
My question : how can I debug this issue ?
