某公司的某 node 上有 8xA100，但是大伙却都挤在一张 500GB 的 SATA 作业，存储甚至没显存高。导致某人在跑实验的时候经常心神不宁，看到随机随时下降的 Avail，恐 No space left on device。

终于在某天晚上某人终于忍不住了，借用 docker

docker run -it --rm --privileged --pid=host quay.io/fedora/fedora:41 nsenter -t $ -a\n

过了把 root 瘾，结果发现这个 node 居然有两个没有挂载的 3T 盘，某人一生炼丹如履薄冰，守着 500G 跑 LLM，想到这里，某人心中顿时悲愤，简单看了下硬盘似乎没有被分区正好自家 lvm 是 xfs，于是分区挂载之，先做个小目标分出来 1 个 T。

看到 Avail 928G，心中舒适了许多。
