AUFS and BLK_DEV_LOOP

[Dry Falls]

@ozsouth
Hi. I had used your DOTconfig from k6.1.38 to build k6.1.42 with the exception of:

Code: Select all

CONFIG_AUFS_FS=y
CONFIG_AUFS_BRANCH_MAX_127=y
# CONFIG_AUFS_BRANCH_MAX_511 is not set
# CONFIG_AUFS_BRANCH_MAX_1023 is not set
# CONFIG_AUFS_BRANCH_MAX_32767 is not set
CONFIG_AUFS_SBILIST=y
# CONFIG_AUFS_HNOTIFY is not set
# CONFIG_AUFS_EXPORT is not set
# CONFIG_AUFS_XATTR is not set
CONFIG_AUFS_FHSM=y
# CONFIG_AUFS_RDU is not set
# CONFIG_AUFS_DIRREN is not set
CONFIG_AUFS_SHWH=y
# CONFIG_AUFS_BR_RAMFS is not set
CONFIG_AUFS_BR_FUSE=y
CONFIG_AUFS_POLL=y
CONFIG_AUFS_BR_HFSPLUS=y
CONFIG_AUFS_BDEV_LOOP=y
# CONFIG_AUFS_DEBUG is not set

as suggested in the aufs documentation.
Just built k6.1.58 with the additional change in

Code: Select all

CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_LOOP_MIN_COUNT=42
...
CONFIG_BLK_DEV_RAM_COUNT=42

and now the init script loads all the sfs modules I would want just like it used to.
This may not be the approved way of doing things, but it works.

@Dry Falls - excellent. DOTconfigs are not easy to understand, but with enough research we can customise effectively.

@Dry Falls Good stuff!

I will also try out some of these adjustments to the DOTconfig with another compile of a full real time version of 6.1.38-rt13 and to get AUFS better integrated in 6.5.2-rt8 and further newer kernel versions patched for both AUFS and full real time.

@Dry Falls, do you mind pointing out where exactly you found this aufs documentation?

Thanks!

Hi porteux. Yes, when building the kernel, the kit downloads aufs<version number> directory and aufs-utils. The first has a documentation folder with Readme. The more general information with configuration options is in the aufs-utils Readme. Everything else is in the manpage which should be included in your kernel-modules/zdrive sfs.

Sorry I didn't see your post sooner.

@porteux I have the documentation for AUFS 6.6 ready as a compressed file!

Thanks a lot, guys!
