  1. Thanks. I tested the card with a PC, and I think you're right. It's dead.
  2. Hi. I'm using Cubietruck, and installed Ubuntu server(mainline) on it. Suddenly, I can't write to disk(SD card). Actually, yes I can. I could create, edit, or even delete files, but all the changes are gone after the Cubietruck is rebooted. The deleted files are back, and created files are gone. What should I check? My SD card is Samsung Evo 16GB, and I'm running Cubietruck for more than 2 years. I have never encountered this weird situation.
  3. Another bloody and gloomy sunday. It hangs again. Same error. (I/O error, dev mmcblk0, sector xxxxxxx) Here the log, but nothing special I think. I'll change the SD card with the same one. And have to wait for another Sundays.. Wish me luck! ;-)
  4. For anyone who might concern. I reinstalled Armbian, and everything works fine so far. If anything happens, I'll post it here. I have no idea what causes this, but I resized(extend the partition to maximum size) the SD card, that could be the reason. This thread might help.
  5. @tkaiser Your advice is always very helpful to me.(to everyone of course.) Thank you again. For the record, my SD card is Samsung Evo plus. I have not known that this SD card is better than average one, because I live in the country where Samsung's HQ is. ;-) And for the conclusion, it would be good not to resize the partiotion. Thank you all.

Armbian monitor is here. http://sprunge.us/aEGY I don't know what you meant by this.
  7. @hrip6 Thanks, But that's not the point that I want to talk about. @tkaiser Thanks again, you've been very helpful. I have one more question. If I extend the partition to the end(like what I did before), is there any possibility that causes any trouble? I don't need to clone this card to another.
  8. I'm using Armbian 5.25(mainline, Ubuntu server) on Cubietruck. The partion is not extended to the full size of the SD card. Here's my results of fdisk -l and df. $ sudo fdisk -l Disk /dev/ram0: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram1: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram2: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram3: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/mmcblk0: 59.6 GiB, 64021856256 bytes, 125042688 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xf3693e57 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 2048 122541823 122539776 58.4G 83 Linux $ df -h /dev/mmcblk0 Filesystem Size Used Avail Use% Mounted on udev 996M 0 996M 0% /dev $ df -h /dev/mmcblk0p1 Filesystem Size Used Avail Use% Mounted on /dev/mmcblk0p1 58G 29G 29G 51% / About 1.6GB is remained in unused space. I know that Armbian needs 128MB emergency swap, but this 1.6GB is for swap? Last time I installed Armbian, I manually steretched the partition to the full size. I'm wondering that might cause this.
  9. For anyone who might be interested in.. Yes, another Sunday has come. It did not frozen, and I could connect to CubieTruck with ssh. However most of commands are not woking. ls works, but ps, lsof, reboot, shutdown... now work. I powered down and remove the SD card, and check it on my desktop PC. Here is the result of fsck. $ sudo fsck.ext4 -v -C 0 /dev/sdc1 e2fsck 1.42.13 (17-May-2015) ArmBuntu: 저널 복구중 (Journal recovering, maybe.)

I can change this card to a new one, but I have to visit the Customer center, or send it to them by mail.. Anyway it takes time. I've just reinstall Armbian again, and wait for another Sunday.
  10. I've been using Armbian 5.2x since last December, but I've got this error 3 weeks ago. I'll wait and see if there's an error this Sunday. If so, then try to change the card.. BTW, I don't understand what you meant, "check the seating".
  11. @tkaiser Thank you for your concern. Here's another one. Which is the log after I tested armbianmonitor -c. http://sprunge.us/WIRS

  13. @tkaiser Thanks. Here's the log. http://sprunge.us/eaYE @Toast If it happens randomly, I would try it.
  14. I'm using CT with Armbian 5.25(mainline) server version. The system hangs on every Sundays, and this is the 3rd time, since it hanged two weeks ago for the first time. When I connected a monitor with it, it says.. mmcblk0 : error -5 sending status command, retrying blk_update_request : I/O error, dev mmcblk0, sector 1503312 .... similar messages are repeated.. I have no idea what causes this. I do not use CRON. I installed these packages. Mpd, nginx, nfs server, samba server, deluge-daemon, pure-ftpd, Resilio Sync. Can anyone help me?
