On a block device with a 4096 byte physical block size and 512 byte logical block size (i.e. so called 512e), mkfs.f2fs creates the file system with 512 byte sectors. # lsblk -t /dev/sdb NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA ...
The logical block size is usually different from the physical block size. The physical block size is usually 512 bytes, which is the size of the smallest block that the disk controller can read or write.Logical block size is set to the page size of the system by default. The default ...
When running mkfs.exfat on a block device with a 4096 byte physical block size and 512 byte logical block size (so called 512e), mkfs.exfat chooses 512 bytes as the file system sector size. # lsblk -t /dev/sdb NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED RQ-SIZE RA...
At VMware, we will continuously keep evaluating way of optimizing. Hence, even though, we support 8K physical sectors sizes with 512 logical block sizes, we will always review ways to optimize where possible. This message is benign and can be safely ignored if the physical sector size is grea...
error:unable to get logical block size for spfile,朋友遇到了这个问题,发来看到后,第一反应是spfile出了问题,可能是被人为修改损坏或文件损坏;排除人为修改导致文件损坏或其它原因的文件损坏
You might enhance the managed system performance by manually or automatically changing the logical-memory block size.
Forcing innodb_redo_log_capacity=1024M does not solve the issue, but gives a different error: Assertion failure: log0files_capacity.cc:320:LOG_WRITER_HARD_CAPACITY_MIN + OS_FILE_LOG_BLOCK_SIZE <= physical_capacity * FREE_FILE_RATIO - OVERHEAD /usr/sbin/mysqld(ut_dbg_assertion_failed(cha...
with the relation between the size of the pack and the size of the logical block of the recording medium being set to 1:n (n: an integer) and the relation between the size of the pack and the size of the physical block of the recording medium being set to 2:m (m: an integer)....
