We can reduce this further in the future, but this is a good
value to keep around. With the advent of continuous healing,
we can be assured that namespace will eventually be
consistent so we are okay to avoid the necessity to
a list across all drives on all sets.
Bonus Pop()'s in parallel seem to have the potential to
wait too on large drive setups and cause more slowness
instead of gaining any performance remove it for now.
Also, implement load balanced reply for local disks,
ensuring that local disks have an affinity for
- cleanupStaleMultipartUploads()
If DiskInfo calls failed the information returned was used anyway
resulting in no endpoint being set.
This would make the drive be attributed to the local system since
`disk.Endpoint == disk.DrivePath` in that case.
Instead, if the call fails record the endpoint and the error only.
bonus make sure to ignore objectNotFound, and versionNotFound
errors properly at all layers, since HealObjects() returns
objectNotFound error if the bucket or prefix is empty.
When crawling never use a disk we know is healing.
Most of the change involves keeping track of the original endpoint on xlStorage
and this also fixes DiskInfo.Endpoint never being populated.
Heal master will print `data-crawl: Disk "http://localhost:9001/data/mindev/data2/xl1" is
Healing, skipping` once on a cycle (no more often than every 5m).
We should only enforce quotas if no error has been returned.
firstErr is safe to access since all goroutines have exited at this point.
If `firstErr` hasn't been set by something else return the context error if cancelled.
Keep dataUpdateTracker while goroutine is starting.
This will ensure the object is updated one `start` returns
Tested with

Fixes#10295
fresh drive setups when one of the drive is
a root drive, we should ignore such a root
drive and not proceed to format.
This PR handles this properly by marking
the disks which are root disk and they are
taken offline.
newDynamicTimeout should be allocated once, in-case
of temporary locks in config and IAM we should
have allocated timeout once before the `for loop`
This PR doesn't fix any issue as such, but provides
enough dynamism for the timeout as per expectation.
Based on our previous conversations I assume we should send the version
id when healing an object.
Maybe we should even list object versions and heal all?
In a non recursive mode, issuing a list request where prefix
is an existing object with a slash and delimiter is a slash will
return entries in the object directory (data dir IDs)
```
$ aws s3api --profile minioadmin --endpoint-url http://localhost:9000 \
list-objects-v2 --bucket testbucket --prefix code_of_conduct.md/ --delimiter '/'
{
"CommonPrefixes": [
{
"Prefix":
"code_of_conduct.md/ec750fe0-ea7e-4b87-bbec-1e32407e5e47/"
}
]
}
```
This commit adds a fast exit track in Walk() in this specific case.
use `/etc/hosts` instead of `/` to check for common
device id, if the device is same for `/etc/hosts`
and the --bind mount to detect root disks.
Bonus enhance healthcheck logging by adding maintenance
tags, for all messages.
