Unable to copy the files to /system/app I am working on i.MX 6Quad SABRE-SD with Android 9. I am facing some problem when copy the some data to system/app from USB Mass Storage,

I got error, when I mount the system to write access:

sabresd_6dq:/ # **mount -o remount,rw '/system'**

**EXT4-fs (dm-0): previous I/O error to superblock detected
Buffer I/O error on dev dm-0, logical block 0, lost sync page write
EXT4-fs (dm-0): re-mounted. Opts: block_validity,delalloc,barrier,user_xattr,acl,inode_readahead_blks=8**


And also I got error when copy the some data to system/app from USB Mass Storage.

sabresd_6dq:/system/app # cp /mnt/media_rw/2A61-DD07/ota/update.zip  /system/app

EXT4-fs error (device dm-0): ext4_mb_generate_buddy:757: group 11, block bitmap and bg descriptor inconsistent: 32768 vs 0 free clusters

EXT4-fs (dm-0): previous I/O error to superblock detected
