Issue #2454 has been updated by Skylar Hawk.
mount_ext2fs now lets me mount the filesystem ro, and everything seems to work fine. However, I am now unable to mount the filesystem r/w, however the output I receive seems to indicate that this is the intended behavior. copying relevant chat messages 16:39 <@tuxillo> try a r/w mount and see what it says 16:42 <@tuxillo> skylrhawk: write anything you need in privmsg 16:46 < skylrhawk> tuxillo: uploading dmsg to pastebin 16:47 < robg> how did you mount the filesystem skylrhawk? 16:48 < skylrhawk> ---> mount_ext2fs /dev/da0s7 /mnt 16:48 < skylrhawk> dmesg --> http://pastebin.com/R8W5VLDc 16:48 < skylrhawk> last line is generated from me trying to mount it 17:02 <@swildner> skylrhawk: so yeah, what it says 17:03 <@swildner> #define EXT2_FEATURE_RO_COMPAT_SUPP EXT2_FEATURE_RO_COMPAT_SPARSE_SUPER 17:03 <@swildner> i think with this, we only support r/o mounting 17:11 < skylrhawk> but the bug I submitted was that it was giving me kernel panic on mount, and previously it let me mount r/w, but now I am unable to mount r/w and for r/o, everything goes smoothly 17:11 < skylrhawk> so I think that's a fair solution 17:12 <@swildner> hmm? 17:12 < skylrhawk> well, to correct myself, it would let me mount, but not do file ops 17:12 < skylrhawk> http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/5f4f1383e0706850f4d42e49fc37813cf7943539 17:12 <@swildner> it let you mount r/w before? 17:12 < skylrhawk> didn't seem to care 17:12 < skylrhawk> but then again, I couldn't touch it 17:12 < skylrhawk> so... 17:13 <@swildner> was the fs created with the sparse superblock feature? 17:14 < skylrhawk> I don't actually know 17:14 <@swildner> (note i have no clue about ext2, so my questions about it might sound dumb) 17:14 <@swildner> ok 17:14 < skylrhawk> created in obsd using newfs.ext2 /dev/sdaj 17:14 < skylrhawk> so default as far as I know 17:15 <@swildner> does "file - </dev/da0s7" show it? 17:17 < skylrhawk> "/dev/stdin: Linux rev 1.0 ext2 filesystem data, UUID=blahblahbla (large files)" 17:20 <@swildner> hm large files.. maybe i'm reading the code wrong and large files is what it doesn't like for r/w 17:20 <@swildner> not sure 17:21 <@swildner> weird though it would survive the mount before tuxillo's change 17:21 < skylrhawk> I don't really know either 17:37 <@vsrinivas> our ext2 works okay if no fancy features are used. 17:37 <@vsrinivas> (no dir_index, sparse super, etc...) 17:38 <@swildner> he has "large files" and it will mount r/o only 17:38 <@vsrinivas> :( 17:38 <@vsrinivas> ok, largefiles should've worked. 17:38 <@swildner> really 17:38 <@vsrinivas> think so.... 17:38 < skylrhawk> ┐(￣ー￣)┌ 17:39 <@vsrinivas> but no other new feature bits must have been on. 17:40 <@vsrinivas> dumpe2fs /dev/whatever | grep 'Filesystem features' 17:43 < skylrhawk> I only get one line: "Filesystem features: large_file" 17:43 <@swildner> ok 17:45 <@vsrinivas> hmm. weird, i think that should work, gonna try something w/ it.

Huete Jimenez Category: Target version: Kernel panic whenever doing operations touching data on an ext2 file system. 14:39 < skylarhwk> I keep getting a kernel panic on release (3.2.1) when I try to do almost any operation on an ext2fs partition 14:39 < skylarhwk> I can provide more information as needed, but can someone possibly help me with it? 14:56 <@tuxillo> skylarhwk: that's normal, it's not in shape 14:56 <@tuxillo> skylarhwk: i plan to work on it soon, if I can. 14:57 < skylarhwk> alright 14:57 <@tuxillo> :( 14:57 < skylarhwk> would the message from the panic help you w/ debugging? 14:57 < skylarhwk> or anything else? 14:57 <@tuxillo> I know it panics already, and I have coredumps 14:57 <@tuxillo> skylarhwk: can you please open a bug at bugs.dragonflybsd.org so that we don't forget about it? 14:57 <@tuxillo> thanks! 14:57 < skylarhwk> sure thing Submitting bug as asked ;) Thanks for for working on it. ^_^ -- You have received this notification because you have either subscribed to it, or are involved in it.
