Hello I'm using the pstore feature to log kernel crashes.
What I observe is that after reboot, always 2 entries are present in the pstore: ls -l /mnt/pstore total 0 -r--r--r-- 1 root root 16372 Jan 1 00:00 dmesg-ramoops-0 -r--r--r-- 1 root root 16372 Jan 1 00:00 dmesg-ramoops-1 If I do not delete the entries and force a new crash, only 2 new entries are available after the system is online again and the older entries are overwritten. The reason for this is that the write index is always initialized to 0 during init. Is this intentional? I would expect that existing entries are kept until they are explicitly deleted or the storage is full. In the latter case the oldest entries can be replaced. Best regards, Ronny
