Мой Raspberry Pi имеет SD-карту на 128 ГБ с Arch ARM и
- Апачи
- NextCloud
установил на него и он, по-видимому, безостановочно взаимодействует с SD-картой. С iotopя узнал, что, mysqldпо-видимому, это процесс, который записывает большую часть данных на диск. В оболочке mysql я затем обнаружил следующее:
show processlist;
+------+--------------+-----------+-----------+---------+------+--------------------------+------------------+----------+

8 rows in set (0.001 sec)
Как мне дать моей SD-карте отдохнуть? /var/logи /tmpуже на ramdisk ( tmpfs)
Затем, когда я непрерывно выполнял show processlistкоманду, я также увидел следующее:
