Looking for help kind of in a hurry. I've been searching google but not finding any options. Is there any way to fix missing /dev paths to luns without rebooting? For example, see the output from lsscsi below. The only way I know to fix this is with a reboot, but I REALLY Need to avoid that if possible. Thanks James [2:0:1:150] disk DataCore Virtual Disk DCS - [2:0:1:151]

Good day to all. i have problems with cdrom hot adding code. currently i using virDomainAttachDevice with type=file, device=cdrom, dev=hdc, this code works for machine with one ide hdd and one ide cdrom, but this not work for machine with only one ide hdd, and i looking for solution to hot add cdrom to machine independent of existing devices or i need way to determinate which target device

Hi libvirt 5.2.0 should support maxGrantFrames setting for xen (changelog). I get ever an error if I use it in the config: <domain type='xen'> <name>satan.chao5.int</name> <uuid>f1f96b1c-fb75-4707-afb7-604d696d29cc</uuid> <memory unit='KiB'>3145728</memory> <currentMemory unit='KiB'>3145728</currentMemory>

Replace the monolithic 'test-max-disks.pl' script with a test program written in C. The program is completely equivalent to the old script, except for the enhancement that it is able to detect if disks are added to the appliance in the wrong order. The tests themselves are split out into some shell scripts: - test-27-disks: Fully tests 27 disks. This is the minimum supported

This is an attempt to fix the issue that some disks' sysfs attributes are not ready at the time its KOBJ_ADD event is sent. The symptom is during device hotplug, udev may fail to find certain attributes, such as serial or wwn, of the disk. As a result the /dev/disk/by-id entries are not created. The cause is device_add_disk emits the uevent before returning, and the callers have to create

Currently the tests fail on x86 with recent kernels: FAIL: test-255-disks.sh This confused me for a while because our other test program (utils/max-disks/max-disks.pl) reports that it should be possible to add 255 disks. Well it turns out that the default amount of appliance memory is sufficient if you're just adding disks, but if you try to add _and_ partition those disks there's

hi all, i would like to ask some questions regarding best practices for zfs recovery if disk errors occur. currently i have zfs boot (nv62) and the following setup: 2 si3224 controllers (each 4 sata disks) 8 sata disks, same size, same type i have two pools: a) rootpool b) datapool the rootpool is a mirrored pool, where every disk has a slice (the s0, which is 5 % of the whole disk) and this

Greetings: I'm upgrading a fileserver running 3.4 (upgrade to a larger disk). I backed up the data from the "old" disk and slapped in a newer, larger disk and installed Centos-3.4. No problems. Now, there are some files on the "old" disk that I forgot to move to the back-up disk, so I'd like to mount the "old" disk as /dev/hdd and reboot the system and

we have CENTOS 4.X on DELL server and one one of virtual disk include 4 disk configure as REID5 (one more disk for hot spare).

Hi all, I would like to knwon if with ZFS it''s possible to do something like that : http://tldp.org/HOWTO/LVM-HOWTO/removeadisk.html meaning : I have a zpool with 48 disks with 4 raidz2 (12 disk). Inside those 48 disk I''ve 36x 3T and 12 x 2T. Can I buy new 12x4 To disk put in the server, add in the zpool, ask zpool to migrate all data on those 12 old disk on the new and

The race condition is noticed between disk_add() and disk attributes, on virtio-blk hotplug. Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that point we haven't created the serial attribute file, therefore depending on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get created. As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk

Suppose I have a single ZFS pool on a single disk; I want to upgrade the system to use two different, larger disks and I want to mirror. Can I do something like: - I start with disk #0 - add mirror on disk #1 (resilver) - replace first disk (#0) with disk #2 (resilver) Casper
