Don't bother with that... It should be enough to just test vol_id: [EMAIL PROTECTED]:~# time /tmp/vol_id-udev113orig --export /dev/sdk /dev/sdk: unknown volume type real 2m1.113s user 0m0.000s sys 0m0.000s [EMAIL PROTECTED]:~# time /tmp/vol_id-udev113patched --export /dev/sdk /dev/sdk: unknown volume type real 0m6.047s user 0m0.000s sys 0m0.000s It's MUCH better with the patch. However I think it is possible to make it even twice as quick, since it generates two I/O errors still: Dec 17 09:36:13 cuba kernel: [3942923.936191] end_request: I/O error, dev sdk, sector 0 Dec 17 09:36:13 cuba kernel: [3942923.946615] Buffer I/O error on device sdk, logical block 0 Dec 17 09:36:16 cuba kernel: [3942926.955903] end_request: I/O error, dev sdk, sector 0 Dec 17 09:36:16 cuba kernel: [3942926.966328] Buffer I/O error on device sdk, logical block 0 In comparsion "fdisk -l /dev/sdk" takes 3 seconds and only one such error is logged per invocation. I can also confirm that the patch does not appear to break anything for reachable devices: [EMAIL PROTECTED]:~# /tmp/vol_id-udev113orig --export /dev/sde ID_FS_USAGE=filesystem ID_FS_TYPE=ext3 ID_FS_VERSION=1.0 ID_FS_UUID=df6f538e-a8b4-4195-91e9-4989cb6bfb45 ID_FS_UUID_ENC=df6f538e-a8b4-4195-91e9-4989cb6bfb45 ID_FS_LABEL=honolulu/mysql ID_FS_LABEL_ENC=honolulu\x2fmysql ID_FS_LABEL_SAFE=honolulumysql [EMAIL PROTECTED]:~# /tmp/vol_id-udev113patched --export /dev/sde ID_FS_USAGE=filesystem ID_FS_TYPE=ext3 ID_FS_VERSION=1.0 ID_FS_UUID=df6f538e-a8b4-4195-91e9-4989cb6bfb45 ID_FS_UUID_ENC=df6f538e-a8b4-4195-91e9-4989cb6bfb45 ID_FS_LABEL=honolulu/mysql ID_FS_LABEL_ENC=honolulu\x2fmysql ID_FS_LABEL_SAFE=honolulumysql Regards -- Tore Anderson -- vol_id takes way too long to finish on unavailable SCSI devices https://bugs.launchpad.net/bugs/156184 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
