- After a recent sysstat (sar) update, I can no longer read my historical sar data:
# sar -f /var/log/sa/sa04 Invalid system activity file: /var/log/sa/sa04 File created using sar/sadc from sysstat version 9.0.4 Current sysstat version can no longer read the format of this file (0x2170) Format of this file had been changed in sysstat-9.0.4-20.el6 due to incompatibility of the certain data types with the current kernel. For more information, please refer to the description of the "--legacy" option in the sar(1) manual page.
- Red Hat Enterprise Linux 6
- sysstat-9.0.4-22.el6 and later
