* admin: configure maintenance tasks via admin.toml
Maintenance task settings could only be edited in the admin UI and live
under <dataDir>/conf, so they silently reverted to defaults whenever the
data directory was recreated. An optional admin.toml now declares vacuum,
balance, and erasure coding settings; keys set there are written through
to the persisted task configs at every startup, overriding UI edits, so
the configuration stays declarative. Generate an example with
"weed scaffold -config=admin".
* vacuum: round min volume age up to whole hours
MinVolumeAgeSeconds was truncated by integer division when converted to
the hour-granular protobuf field, so a sub-hour setting silently became
0 and disabled the age guard.
* admin: split and normalize preferred_tags from admin.toml
A comma-separated string, as set via environment variable, came through
viper as a single slice element. Split on commas and reuse
util.NormalizeTagList, matching the plugin config path.
* scaffold: clarify admin.toml wording
* [CheckDisk][GRPC]: implement MVP for disk health detection, added timeout for new grpc connections
* fix(volume): build disk health check on every platform
setDiskStatus only existed behind the statfs build tag, so disk.go failed
to compile on windows, openbsd, solaris, netbsd and plan9. Move the timeout
wrapper and failure tracking into the shared disk.go and have each platform's
fillInDiskStatus return an error, so every platform gets the same protection
from a stuck filesystem.
Also restore the uint64(fs.Bavail) cast: Bavail is int64 on freebsd, so the
unguarded multiply broke the freebsd build.
* fix(volume): keep one outstanding statfs probe per disk
A stuck statfs used to leave isChecking cleared by the timeout path, so the
next check spawned another goroutine while the previous one was still blocked
in the syscall, leaking one goroutine per minute on a hung disk. Clear the
flag only when statfs returns and treat an overlapping check as a failure, so
a hung filesystem keeps a single outstanding probe and still gets reported.
* fix(volume): assume disk available until the first health check
isDiskAvailable defaulted to false, and CollectHeartbeat skips locations that
are not available. A freshly started volume server would therefore omit every
volume from its first heartbeats until the async CheckDiskSpace ran, so the
master could briefly treat all of them as missing.
* fix(volume): label the disk error metric by data directory
The new gauge tagged the series with IdxDirectory while every neighbouring
resource gauge uses Directory, so the error series would not line up with them
in dashboards. Also log the underlying error instead of a generic message.
* test(volume): cover disk health success and repeated-failure paths
* fix(volume): make a healthy disk the zero-value default
Track the disk as isDiskUnavailable instead of isDiskAvailable so the safe
state is the zero value, matching isDiskSpaceLow. CollectHeartbeat only skips a
location once a check has actively marked it unavailable, so any DiskLocation
built without running CheckDiskSpace (tests, future call sites) still reports
its volumes instead of silently dropping them.
* feat(disk): detect degraded disks using IO latency probes
* feat(stats): introduce configurable disk I/O health probe with EWMA-based latency detection
* feat(disk): replace EWMA with sliding window algorithm for disk health detection and added user-friendly options
* feat(disk): improve disk health probing and recovery
* feat(volume): configure disk health checks via volume.toml
* fix(volume): Remove disk IO probe CLI options

* refactor(command): expand "~" in all path-style CLI flags
Many of weed's path-bearing flags (-s3.config, -s3.iam.config,
-admin.dataDir, -webdav.cacheDir, -volume.dir.idx, TLS cert/key
files, profile output paths, mount cache dirs, sftp key files, ...)
were never run through util.ResolvePath, so a value like "~/iam.json"
was used literally. Tilde only worked when the shell expanded it,
which silently fails for the common -flag=~/path form (bash leaves
the tilde literal in --opt=~/path).
- Extend util.ResolvePath to also handle "~user" / "~user/rest",
matching shell tilde expansion. Add unit tests.
- Apply util.ResolvePath at the top of each shared start* function
(s3, webdav, sftp) so mini/server/filer/standalone callers all
inherit it; resolve at the few one-off use sites (mount cache
dirs, volume idx folder, mini admin.dataDir, profile paths).
- Drop the duplicate expandHomeDir helper from admin.go in favor of
the now-equivalent util.ResolvePath.
* fixup: handle comma-separated -dir flags for tilde expansion
`weed mini -dir`, `weed server -dir`, and `weed volume -dir` accept
comma-separated paths (`dir[,dir]...`). Calling util.ResolvePath on
the whole string mishandled multi-folder values with tilde, e.g.
"~/d1,~/d2" would resolve as if "d1,~/d2" were a single subpath.
- Add util.ResolveCommaSeparatedPaths: split on ",", run each entry
through ResolvePath, rejoin. Short-circuits when no "~" present.
- Use it for *miniDataFolders (mini.go), *volumeDataFolders (server.go),
and resolve each entry of v.folders in-place (volume.go) so all
downstream consumers see resolved paths.
- Add 7-case TestResolveCommaSeparatedPaths covering empty, single,
multiple, and mixed inputs.
* address PR review: metaFolder + Windows backslash
- master.go: resolve *m.metaFolder at the top of runMaster so
util.FullPath(*m.metaFolder) on the next line sees an expanded
path. Drop the now-redundant ResolvePath in TestFolderWritable.
- server.go: same treatment for *masterOptions.metaFolder, paired
with the existing cpu/mem profile resolves. Drop the redundant
inner ResolvePath at TestFolderWritable.
- file_util.go: ResolvePath now accepts filepath.Separator as a
separator after the tilde, so "~\\data" works on Windows. Other
platforms keep current behaviour (backslash stays literal because
it is a valid filename character in usernames and paths).
- file_util_test.go: add two cases using filepath.Separator that
exercise the new code path on Windows and remain a no-op on Unix.
* address PR review: resolve "~" in remaining command path flags
Comprehensive sweep of path-bearing flags across every weed
subcommand, applying util.ResolvePath in-place at the top of each
run* function so all downstream consumers see expanded paths.
- webdav.go: resolve *wo.cacheDir at the top of startWebDav so
mini/server/filer/standalone callers all inherit it.
- mount_std.go: cpu/mem profile paths.
- filer_sync.go: cpu/mem profile paths.
- mq_broker.go: cpu/mem profile paths.
- benchmark.go: cpuprofile output path.
- backup.go: -dir resolved once at runBackup; drop the duplicated
inline ResolvePath in NewVolume calls.
- compact.go: -dir resolved at runCompact; drop inline ResolvePath.
- export.go: -dir and -o resolved at runExport; drop inline
ResolvePath in LoadFromIdx and ScanVolumeFile.
- download.go: -dir resolved at runDownload; drop inline.
- update.go: -dir resolved at runUpdate so filepath.Join uses the
expanded path; drop inline ResolvePath in TestFolderWritable.
- scaffold.go: -output expanded before filepath.Join.
- worker.go: -workingDir expanded before being passed to runtime.
* address PR review: resolve option-struct paths at run* entry points
server.go:381 propagates s3Options.config to filerOptions.s3ConfigFile
*before* startS3Server runs, which meant the filer-side code saw the
unresolved tilde-prefixed pointer. Same pattern for webdavOptions and
sftpOptions (and equivalent in mini.go / filer.go).
The fix: hoist resolution from the shared start* functions up to the
run* entry points, where every shared pointer is set up before any
propagation happens.
- s3.go, webdav.go, sftp.go: extract a resolvePaths() method on each
Options struct that runs every path field through util.ResolvePath
in-place. Idempotent.
- runS3, runWebDav, runSftp: call the standalone struct's resolvePaths
before starting metrics / loading security config.
- runServer, runMini, runFiler: call resolvePaths on every embedded
options struct, plus resolve loose flags (serverIamConfig,
miniS3Config, miniIamConfig, miniMasterOptions.metaFolder, and
filer's defaultLevelDbDirectory) so they're expanded before any
pointer copy or use.
- Drop the now-redundant inline ResolvePath at filer's
defaultLevelDbDirectory composition.
* address PR review: re-resolve mini -dir post-config, cover misc paths
- mini.go: applyConfigFileOptions can overwrite -dir with a literal
~/data from mini.options. Re-resolve *miniDataFolders after the
config-file apply, alongside the other path resolves, so the mini
filer no longer ends up with a literal ~/data/filerldb2.
- benchmark.go: resolve *b.idListFile (-list).
- filer_sync.go: resolve *syncOptions.aSecurity / .bSecurity
(-a.security / -b.security) before LoadClientTLSFromFile.
- filer_cat.go: resolve *filerCat.output (-o) before os.OpenFile.
- admin.go: drop trailing blank line at EOF (git diff --check).
* address PR review: resolve -a.security/-b.security/-config before use
Three follow-up fixes:
- filer_sync.go: the -a.security / -b.security resolves were placed
*after* LoadClientTLSFromFile / LoadHTTPClientFromFile were called,
so weed filer.sync -a.security=~/a.toml still passed the literal
tilde path. Hoist the resolves above the security-loading block so
TLS clients see expanded paths.
- filer_sync_verify.go: same flag pair was never resolved at all in
the verify command; resolve at the top of runFilerSyncVerify.
- filer_meta_backup.go: -config (the backup_filer.toml path) was
passed directly to viper. Resolve at the top of runFilerMetaBackup.
- mini.go: master.dir defaulted to the entire comma-joined
miniDataFolders. With weed mini -dir=~/d1,~/d2 (or any multi-dir
setup), TestFolderWritable then stat'd the joined string instead
of a single directory. Default to the first entry via StringSplit
to mirror the disk-space calculation a few lines below, and drop
the now-redundant ResolvePath in TestFolderWritable.
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.
