在启用或禁用 SLES 的软件库前,要先注册此 SLES
# SUSEConnect --list-extensions
# SUSEConnect -p sle-module-live-patching/15.3/x86_64
(补充:这里以启用 sle-module-live-patching/15.3/x86_64 软件库为例)
# SUSEConnect -d -p sle-module-basesystem/15.3/x86_64
(补充:这里以禁用用 sle-module-live-patching/15.3/x86_64 软件库为例)
# SUSEConnect -r <ActivationCode> -e <EmailAddress>
(补充:这里的 <ActivationCode> 和 <EmailAddress> 是在注册了 SUSE 账号并购买了对应的的订阅以后获得)
# SUSEConnect –de-register
或者:
# SUSEConnect -d
# SUSEConnect --cleanup
# rm -f /etc/SUSEConnect
# rm -rf /etc/zypp/credentials.d/*
# rm -rf /etc/zypp/repos.d/*
# rm -f /etc/zypp/services.d/*

kernel: [829455.595333][ C10] critical target error, dev sda, sector 104056241 op 0x3:(DISCARD) ......
如果是在 VMware 上运行的虚拟机在日志里出现 critical target error 此类报错,尤其是涉及到 DISCARD 操作的错误,通常是由 VMware 进行硬盘垃圾空间回收或者进行硬盘优化造成的。
VMware 的控制平台上,检查宿主机的硬盘是否正常。若不正常则修复或者更换硬盘。
