Hi I get this problem running my ubi/ubifs on a partition in my system. The error occurs when I try to move one file to a new location and there seems to be something wrong with the file. The file contains binary data and is 9.3MB large. Can anyone help me locate this error or point me in the right direction? My system is a ap7002(arch == avr32) with 32MByte SRAM, 8MByte NOR flash and 2GByte NAND flash(ubi).

If there is no interesting/insighting information, could you please also enable UBIFS messages and send them. Please, glance here: http://www.linux-mtd.infradead.org/doc/ubifs.html#L_how_send_bugreport

On the bottom there is a general printout from the init of the ubi/ubifs on boot with dbg enabled.

OK. > Wpr_004.wfp originates from a vfat partition, and was moved along with 10 other files, and then when I try to move the file back out from ubifs the read error occurs. OK, this means that the file had not been correctly written to UBIFS. Your NAND driver may have problems. The fact that you use NAND flash with 4KiB page size also suggests this, because AFAIK MTD does not really support 4KiB per page NANDs. You probably have some custom MTD diver/modifications. Could you please verify your NAND driver before trying to use UBIFS? Here you may get NAND tests which should do this: git://git.infradead.org/users/ahunter/nand-tests.git The tests are kernel modules. Compile them properly, then just insert them, may be with some parameters. Use modinfo to see the parameters, or look at the source code. All tests are harmless, except of torture test - be careful with it. Note, these tests has not been run on 4KiB-page NANDs, but they should work fine anyway.

Basically, you have broken nodes on your flash media, which means your files have not been written correctly for some reasons. For now I suspect buggy NAND driver. > How do I do cleaning in ubifs? Well, in _normal_ situations you should not need this at all, and UBIFS is self-recoverable. In your case you have some severe problems so you have data corruptions which you cannot recover anyway. You may only delete the corrupted files. But yes, an ckfs.ubifs user-space utility would be nice to have, and we were thinking to create it. At the moment, it does not exist.

This is ran on a SLC Samsung NAND flash(2GByte). Thank you for all the help so far. After fixing ( I think ) I ran the tests and I am adding the results from the pagetest and subpagetest. Here where the only test with some errors. Any hint to what to look into next would be great.

It is weird that you do not have sub-pages if this is SLC. You waste 4KiB per eraseblock because of this. Here you may find what is sub-page: http://www.linux-mtd.infradead.org/faq/ubi.html#L_find_min_io_size If your flash allows sub-pages, I'd recommend to support them. > Any hint to what to look into next would be great. No, not really. You should dig your NAND driver.
