Hi Amir, I followed your guide, for the most part it is okay, this is what i did: 1. git clone git://github.com/amir73il/next3-utils.git -b next3-stable That went ok. 2. git clone git://github.com/amir73il/ext4-snapshots.git -b next3-stable ~/next3-utils/linux-2.6.35.9 That gave the error: Cloning into /root/next3-utils/linux-2.6.35.9... fatal: remote error: access denied or repository not exported: /0/nw/0f/29/37/17467/1022288.git I changed "git clone git://github.com/amir73il/ext4-snapshots.git -b next3-stable ~/next3-utils/linux-2.6.35.9" to " git clone https:// github.com/amir73il/ext4... etc" than it downloaded the git. 3. I downloaded the tar ball from kernel.org i hope that was the right place. Make next3_snapshot went ok, and i copied the patch file to the correct dir. on "make module" i get this error: /root/next3-utils/next3/inode.c: In function ‘next3_write_begin’: /root/next3-utils/next3/inode.c:1983: error: redeclaration of ‘page_bufs’ with no linkage /root/next3-utils/next3/inode.c:1981: error: previous declaration of ‘page_bufs’ was here make[4]: *** [/root/next3-utils/next3/inode.o] Error 1 make[3]: *** [_module_/root/next3-utils/next3] Error 2 make[2]: *** [sub-make] Error 2 make[1]: *** [all] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.32-5-amd64' make: *** [module] Error 2 so in inode.c i removed line 1983 "struct buffer_head *page_bufs;" because it is double. after that it compiles correct. sudo make test gives: (test -f test.img && (./bin/tunefs.next3 -l test.img | grep UUID)) || \ ( touch test.img ; ./bin/truncate -s 4G test.img ; yes | ./bin/next3 mkfs test.img ) /bin/sh: ./bin/truncate: not found /bin/sh: ./bin/next3: Permission denied make: *** [test] Error 126 so i did: chmod +x ./bin/next3 cp /sbin/tunefs.next3 /root/next3-utils/bin/ gcc ./bin/truncate.c -o ./bin/truncate ./bin/next3 config /dev/loop0 /root/next3-utils/test than i did a make test again, this time it was ok. I installed this module and tested for 2 days, but it crashed again with the kernel bug. there where no more errors on snapshot size... this is what i got: Apr 28 00:13:29 nl-gouda-07 kernel: [14035.935096] snapshot: snapshot (40) created Apr 28 00:13:29 nl-gouda-07 kernel: [14036.117712] snapshot: snapshot (40) activated Apr 28 00:13:29 nl-gouda-07 kernel: [14036.119889] snapshot: snapshot (40) has been taken Apr 28 00:18:56 nl-gouda-07 kernel: [14362.959709] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:19:33 nl-gouda-07 kernel: [14399.801548] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:19:34 nl-gouda-07 kernel: [14401.122780] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:27:52 nl-gouda-07 kernel: [14898.977055] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:37:58 nl-gouda-07 kernel: [15505.167611] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:48:05 nl-gouda-07 kernel: [16111.976134] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 00:58:02 nl-gouda-07 kernel: [16708.266859] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:01:02 nl-gouda-07 kernel: [16888.743711] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:06:57 nl-gouda-07 kernel: [17243.999541] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:10:24 nl-gouda-07 kernel: [17450.672739] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:16:40 nl-gouda-07 kernel: [17826.835838] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:23:44 nl-gouda-07 kernel: [18250.445274] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:50:52 nl-gouda-07 kernel: [19878.965699] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:54:07 nl-gouda-07 kernel: [20073.717882] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 01:56:21 nl-gouda-07 kernel: [20207.764348] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 02:03:44 nl-gouda-07 kernel: [20651.138282] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 03:10:58 nl-gouda-07 kernel: [24684.735273] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:03:26 nl-gouda-07 kernel: [31432.762010] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:03:27 nl-gouda-07 kernel: [31433.424412] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:04:12 nl-gouda-07 kernel: [31478.818662] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:04:51 nl-gouda-07 kernel: [31518.054273] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:07:28 nl-gouda-07 kernel: [31674.387931] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:07:35 nl-gouda-07 kernel: [31681.206298] NEXT3-fs warning (device dm-1): next3_block_to_path: block < 0 Apr 28 05:07:54 nl-gouda-07 kernel: [31700.680536] snapshot: next3_snapshot_get_undo_access(b:0/67399) failed!

Date: 04/27/2012 08:34 PM Subject: Re: [Next3-users] Kernel bug.. Hi Kim, ext4 snapshots is not available for kernel 2.6.32, only for kernel 2.6.38 and above. Also it is in a less stable state then next3. So if you are going to use it for production, next3 is preferred. ext4 snapshots would give you some performance benefits, since ext4 performs better than ext3 in several benchmarks. Regarding the next3 release, I need to refresh my memory, so I'll give you initial pointers and you can tell me what's missing. You will need to get (instructions assume you run this in your home dir): 1. The next3 utils: ~$ git clone git://github.com/amir73il/next3-utils.git -b next3-stable 2. Linux tree with next3 sources. The next3-stable branch is based off stable kernel 2.6.35.9, so check it out like this: ~$ git clone git://github.com/amir73il/ext4-snapshots.git -b next3-stable ~/next3-utils/linux-2.6.35.9 3. a tar ball of linux-2.6.35.9 and place it at: ~/kernel/2.6.35/linux-2.6.35.9.tar.bz Then run: ~$ cd ~/next3-utils/patch ~/next3-utils/patch$ make next3_snapshot This may take some time to unpack files from kernel tar ball and should eventually create the patch file next3_snapshot.module.patch and copy it to the ~/kernel/2.6.35/ dir. This is the same patch that is being downloaded from the web site for all supported kernels (2.6.31-35). If you copy it to ~/next3-util and run 'make module' in that directory, it should build the latest next3 version for your kernel (2.6.32), which you can test by running 'sudo make test'. I am pretty sure I missed something in the instructions, so please let me know how far you got and we'll take it from there. Thanks, Amir.
