[Starlingx-discuss] Where did my RAM go?
Hi! i have real RAM problems at my worker nodes, they are equipped with 256GB RAM. unfortunately i can only use a fraction of it for my VMs and i don't understand why? maybe someone can explain to me where all the RAM went? compute-0:~$ cat /proc/meminfo MemTotal: 263854428 kB MemFree: 25030424 kB MemAvailable: 24584388 kB Buffers: 35308 kB Cached: 350236 kB SwapCached: 0 kB Active: 27306600 kB Inactive: 236124 kB Active(anon): 27168144 kB Inactive(anon): 8936 kB Active(file): 138456 kB Inactive(file): 227188 kB Unevictable: 5424 kB Mlocked: 5424 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 132 kB Writeback: 0 kB AnonPages: 27162864 kB Mapped: 99272 kB Shmem: 15880 kB Slab: 912816 kB SReclaimable: 132552 kB SUnreclaim: 780264 kB KernelStack: 40256 kB PageTables: 107948 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 27069612 kB Committed_AS: 47150896 kB VmallocTotal: 34359738367 kB VmallocUsed: 823656 kB VmallocChunk: 34224520432 kB HardwareCorrupted: 0 kB CmaTotal: 16384 kB CmaFree: 2114464 kB HugePages_Total: 200 HugePages_Free: 200 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB DirectMap4k: 18644 kB DirectMap2M: 5122048 kB DirectMap1G: 263192576 kB compute-0:~$ free total used free shared buff/cache available Mem: 263854428 237596844 24955580 15880 1302004 24512988 Swap: 0 0 0 there are two running VMs, one is allocate 32GB and the other one 512MB but the server has only 24GB left? whats going on? this is an dual CPU system with 16x16GB slots full filled.
