This problem is caused by “NTFS-3G". Im quite sure about it. NTFS-3G version 2017 or before. Would lead to this problem. I've test 23.5 bookworm, the newest version image for Orange Pi Zero 2. In this version of image, NTFS-3G version is 2022.10.3. And it works fine. No more stuck. I asked a question related to usb removable disk before, but now it is proved that the stuck is not caused by the UAS driver.

Let me think about how to descript this situation...... I have a movable disk and mount in path: /mnt/sba1 It happened first time when I using a program called "Syncthing" , I try to sync my file into my movable disk. I get lot of files in my directory. When the "Syncthing" start scanning. the system will stuck. Not that kind of whole system stuck, but only if you trying to read anything about /mnt/sda1. If you trying to "df -h", you'll get stuck. "fdisk -l", stuck. "cd /mnt/sba1", stuck again. "mount" "umount" "lsblk" all will be stuck. Such like this ...... Reboot the system is only way to restore. No need to unplug the disk. Just reboot and get normal. So I tried writing a Golang program, the program will read huge number of files in my disk instantly. Yes, stuck again. So I came to the conclusion: When I try to read a large number of files, there will be a malfunction. I thought it's about usb driver problem, so I change "UAS" to "USB-Storage". Still stuck again and again. ( With this topic : How can I change usb-disk driver "UAS" to "usb-storage" ? ) I change 3 Orangepi Zero2 board and 3 different movable disk, Still like this. Right now,I'm writing this post, the situation has reappeared, again...... root@OPIZ2-0146:/# ulimit -n 102400 root@OPIZ2-0146:/# ulimit -a real-time non-blocking time (microseconds, -R) unlimited core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 3756 max locked memory (kbytes, -l) 123522 max memory size (kbytes, -m) unlimited open files (-n) 102400 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 3756 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited root@OPIZ2-0146:/# cat /proc/sys/fs/file-max 9223372036854775807 How can I locate the cause of this problem?

I run "armbianmonitor -u" and I got this : https://paste.armbian.com/bapohonaja My SBC is orangepi zero 2, and I tried to use it as a NAS. But sometime the system hangup because I push to much file in my usb-disk. And I G**gle about it. Somebody said because usb driver is "UAS". So I use command "lsusb -t" and bingo, my usb driver is "uas": ``` >: lsusb Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 152d:0562 JMicron Technology Corp. / JMicron USA Technology Corp.

I tried "/boot/armbianEnv.txt" with "usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u,0x152d:0x0562:u" and "update-alternatives -u" and reboot but failed. Still "uas" there! Is that posible to change "uas" driver to "usb-storage"?
