the value is longer than the number of server CPUs, then the CPU resources are insufficient.B, is the block's abbreviation, indicating the number of processes waiting for the resource. b means that the process is blocked by resources other than the CPU (hard disk or network), in a waiting state, the card is dead, B is blocked. For example, the speed is slow, the process wants to send you a packet, if the network speed quickly, only 1 seconds to send the finished. But now slow, it may take 10 se

Summary: Fsync need sync file modification and metadata; Fdatasync only sync metadata when necessary to save a file sync operation. Berkeley DB ensures that Fdatasync does not go to sync metadata by pre-setting the log file size. Here is a simple list of the corresponding BDB code:OS/OS_FSYNC.C:__os_fsync ()if(Db_global (j_fsync)! =NULL) ret= Db_global (J_

Such a mistakeThis is mainly because the logical volume allows the maximum number of logical partitions to be 512 by default, so when the logical volume size exceeds this limit, 0516 is report
