সেন্টওএস ইনস্টল করার পরে, আমি কয়েকটি লাইন দেখতে
/dev/mapper/centos_jackpc--11-swapএবং
/dev/mapper/centos_jackpc--11-rootযখন আমি ইস্যু fdisk -l।
এগুলির উদ্দেশ্য কী? এবং কেন তারা উবুন্টুর পক্ষে দেখায় না?
সম্পূর্ণ fdisk -lএখানে প্রদর্শিত হয়:

/dev/mapperনেই অগত্যা লজিক্যাল ভলিউম LVM। তবে এইগুলি দেখতে তাদের মতো দেখাচ্ছে। (
