Bug 362809 – disk gets renamed after return from suspend

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Fatih 2011-04-10 08:45:06 UTC]

I have a swap space activated on external disk sda1. After pm-suspend this partition gets deleted (gets new name sdb1) and I keep getting "Read-error on swap-device". 

I found a discussion relating to this problem (with swap file, not partition) in linux mailing list. It appears that the suggested solution has been implemented and I found it on current kernel but it does not seem to be preventing this from happening on swap partitions.

http://kerneltrap.org/mailarchive/linux-kernel/2008/10/18/3717844

vim +1984 /usr/src/linux/fs/namei.c

        if (check_sticky(dir, victim->d_inode)||IS_APPEND(victim->d_inode)||
            IS_IMMUTABLE(victim->d_inode) || IS_SWAPFILE(victim->d_inode))
                return -EPERM;



Reproducible: Always

Steps to Reproduce:
1. swapon /dev/sda1 where sda1 is a swap partition on external disk
2. pm-suspend 
3. wake up
4. observe kernel logs for "Read-error on swap-device" and /proc/swaps for deleted nodes
Actual Results:  
# grep "Read-error" /var/log/messages
kernel: [176743.130572] Read-error on swap-device (8:0:152)

# grep sda1 /proc/swaps 
/dev/sda1\040(deleted)                  partition	1048572	6812	1

# swapoff /dev/sda1
swapoff: /dev/sda1: swapoff failed: No such file or directory

# ll /dev/sda1
ls: cannot access /dev/sda1: No such file or directory

# ll /dev/sdb1
brw-rw---- 1 root disk 8, 17 Apr 10 10:19 /dev/sdb1

# swapoff /dev/sdb1 
swapoff: /dev/sdb1: swapoff failed: Invalid argument



Expected Results:  
# grep "Read-error on swap-device" /var/log/messages
# grep sda1 /proc/swaps 
/dev/sda1                               partition	1048572	6812	1

Can you also attach your dmesg output? Does this occur only with a 2.6.38 kernel?

I don't think the discussion from LKML has something to do with this bug.

I'm not sure that this is a kernel bug either. And maybe tweaking udev rules could fix your problem.
