There are superblock, group descriptor table, inode bitmap, data bitmap , inode table ,etc. As I understood. these are stored in virtual memory sequentially.
- Are these metadata(superblock, group descriptor table, inode bitmap, data bitmap , inode table ,etc) of filesystem stored in SSD sequentially?
- Does a block in SSD , which contains pieces of file system, contains only filesystem data(metadata)?
- I know that if I repeatedly read the same physical address in SSD, atime(access time) of inode is updated. Is block in SSD, which contains atime, Garbage collected so that the data in the GCed block move to another free block. what i am saying is only read operation can cause GC.
