KDL: get_writable_cached_block: invalid block number 119165821333100 (max 2618594)

[kaoutsis]

'haiku-src' is mounted read-only, as it may contains bad data. I took the naive approach: copy from that volume to the home dir the 'develop' dir via tracker (~280000 files)

revision is hrev24806, Haiku boot volume is a newly created partition /dev/hda8 and the haiku installation have been created from a linux machine with jam -q @disk

[kaoutsis]

a part of the serial log starting from the point where the haiku-src volume is mounted

That's just a panic used for debugging - it just shows that your disk indeed was corrupted, and therefore should be mounted read-only indeed.

However, judging from the stack crawl, there seem to be some code paths that will try to write to a disk even though it's mounted read-only. Will have a look at that.

[kaoutsis]

i rebooted the machine, and boot again to Haiku from the same as previously partition (grub terminology hd0,7): What i see now is, the desktop starts with the Installer program

[kaoutsis]

Replying to kaoutsis:

What i see now is, the desktop starts with the Installer program

it looks like the root device is now read-only, the replay log failed, a part from syslog (after the reboot) 'Haiku' is the name of the root device i wanted to boot as previously

bfs: Replay log, disk was not correctly unmounted...
run count: 1002310361, array max: 15, max runs: 126
bfs: Log entry has broken header!
bfs: replaying log entry from 656 failed: Bad data
bfs: Replaying log failed, data may be corrupted, volume read-only.
bfs: mounted "Haiku" (root node at 524288, device = /dev/disk/ata/0/master/1_3)

Should be fixed with hrev24809. Note, you might still experience this panic with a corrupt disk, though. If it's a read-only volume, it just shouldn't try to get a writable block this way :-)

If it annoys you, you can safely turn that panic into a dprintf - we'll need to do that before an eventual release anyway.

Damn Trac! What I meant to say was: We might want to refine the way how the Bootscript detects a CD boot (or find a better way on what happens when a volume might be corrupt) :-)

Either way, was the Haiku volume freshly created with a current revision (after all those block cache changes)? If so, please reopen #2024, as the log corruption should have been fixed already.

Replying to axeld:

I'm afraid yes, this 'Haiku' volume was created with hrev24806. The corruption happen during the copying process. NOTE: this 'Haiku' device is hd0,7 and has nothing to do with 'Haiku' device hd1,7 from ticket #2024 which was created by hrev24775 also by i clean install jam -q @disk (i have already sent you the superblock and the log region for this partition) However the two partitions have one common characteristic: have been corrupted by haiku, during a copying process.

If so, please reopen #2024, as the log corruption should have been fixed already.

Ok, ticket #2024 is open. I will check if the corruption still occurs with hrev24809, and i will report later:-)

[kaoutsis]

ok i checked hrev24809 fresh Haiku partition: the replaying log failed:

bfs: Replay log, disk was not correctly unmounted...
run count: 1002310361, array max: -1, max runs: 126
bfs: Log entry has broken header!
bfs: replaying log entry from 656 failed: Bad data
bfs: Replaying log failed, data may be corrupted, volume read-only.
bfs: mounted "Haiku" (root node at 524288, device = /dev/disk/ata/0/master/1_3)
module: Search for file_cache/launch_speedup/v1 failed.
bfs: volume reports 418982 used blocks, correct is 401812  

so we are moving to 2024, this ticket should be closed?

oh sorry, the ticket is closed
